INTRODUCTION  
ABSTRACT  
One point of intersection between Psychology and  
Law is the analysis of criminal behavior. In this context,  
one of the most relevant debates is the relationship  
between criminality and the presence of psychological  
disorders (Jácome et al., 2023). Although there is a  
connection between personality and delinquency  
Human-Hendricks & Roman, 2014; Aguirre et al.,  
013), this relationship is complex and cannot be  
considered in a unidimensional way (Manunza &  
Giampaolo, 2018).  
This link between mind and law directly influences  
the concept of imputability, which is the foundation of  
legal responsibility. Imputability implies the attribution  
of an act and its consequences to a person, which  
justifies that person being held accountable to society  
for his or her actions, whether positive or negative.  
Without imputability, true responsibility cannot exist  
This article presents a systematic review on the  
legal responsibility of individuals diagnosed with  
Antisocial Personality Disorder from 2018 to 2024. In  
recent years, a debate has been maintained on the legal  
treatment of psychiatric disorders, including personality  
disorders, due to the complexity in managing their  
imputability in the legal system. The PRISMA model  
criteria were used to review and select studies relevant  
to this objective in academic databases. The results  
show that there is evidence of alterations at the  
neuroanatomical level that may affect the volitional  
capacity of people with APD, resulting in poor impulse  
control. However, some authors agree that, despite these  
alterations, individuals with this diagnosis are fully  
aware of their actions and their consequences when  
committing a crime, so this diagnosis would not  
necessarily constitute a reason for mitigation of their  
imputability. This article highlights the importance of  
continuing to develop theory and evaluation methods to  
establish adequate legal treatment.

(
Ronco, 2014).  
In this context, the literature agrees on the fact that  
the concept of imputability is based on three main axes.  
On the one hand, typicality is considered, a concept that  
implies that every action or omission contemplated in  
the legal field must be contained in some criminal type.  
To determine this, an objective typicality analysis  
process must be carried out, where it is understood that  
the acts committed are directly classified in a legal  
document, and subjective typicality, which has to do  
with those acts that, although they are not specifically  
classified in a legal type, there are antecedents of similar  
situations in which the jurisprudence has ruled on a  
certain legal action (Mata, 2020).  
Keywords: imputability, antisocial personality  
disorder, psychopathy, legal responsibility.  
RESUMEN  
Este artículo presenta una revisión sistematizada  
sobre la responsabilidad legal de individuos  
diagnosticados con Trastorno de Personalidad  
Antisocial en el período 2018 - 2024. En los últimos  
años se ha mantenido un debate sobre el tratamiento  
legal de trastornos psiquiátricos, incluyendo los  
The second axis on which the concept of  
imputability is based is unlawfulness, within which it

https://www.sa-rj.net/index.php/sarj/article/view/48  
must be ruled out that the act in question does not have  
any cause of justification, which determines that said  
action or omission is contemplated in the Law (Arias et  
al., 2022). Finally, culpability must be considered, that  
is, that the individual had prior knowledge of the act  
committed and its consequences (Mata, 2020).  
The Diagnostic and Statistical Manual of Mental  
Disorders DSMV-TR (American Psychiatric  
Association [APA], 2019) defines personality disorders  
as “an enduring pattern of internal experience and  
behavior that departs markedly from the expectations of  
the subject's culture” (p. 733).  
Taking into account the above, for an individual to  
be considered accountable, it is necessary that he or she  
has sufficient cognitive abilities to have the capacity for  
self-determination and freedom to decide. Therefore,  
when a possible crime is committed, it is necessary to  
determine that the subject has acted in accordance with  
his or her free will, and that said actions have been  
previously reasoned and that there has been a conscious  
decision-making process regarding the fact and its  
consequences.  
Another concept associated with imputability is  
criminal conduct, understood as those behaviors that  
deliberately transgress the norms and all forms of social  
control that monitor compliance with coexistence  
guidelines dictated by a legal framework (Chirino &  
Giménez, 2018). This type of behavior can be  
considered an expression of the particular  
psychopathology of the perpetrator of the crime, in the  
event of a psychic disorder. These aspects of the  
individual's personality must be subject to examination,  
because it could be determined that his condition of  
mental pathology implies an alteration of his cognitive  
and volitional capacities, and, therefore, that he is not  
imputable.  
Therefore, the concept of imputability, defined as  
the determination that a person is subject to a penalty  
established by law (Casanueva, 2014), is closely related  
to psychological factors, since it implies that the subject  
has a set of minimum psychic faculties to be aware of  
his actions, and that there is no alteration of his will at  
the time of "deciding" to commit them.  
However, individuals with a personality disorder  
have symptomatic characteristics that may predispose  
them to the manifestation of criminal behavior, such as  
impulsiveness, emotional coldness, and lack of empathy  
Additionally, the International Classification of  
Diseases ICD-11 (World Health Organization [WHO],  
2019) stipulates that personality disorders involve an  
alteration of some aspects of the self, such as identity,  
self-esteem, self-perception and self-direction, in  
addition to interpersonal dysfunctions, such as the  
ability to develop and maintain close relationships,  
understand the points of view of others, and resolve  
interpersonal conflicts.  
To assess personality disorders, it is proposed, first  
of all, to assess the presence of this type of alterations,  
and to identify whether these are of late onset, since in  
that case they would not be considered a personality  
disorder. On the other hand, it is necessary to stipulate  
the severity of the alterations, since, if they do not meet  
a minimum requirement of severity, they could not be  
considered a disorder, but a personality difficulty.  
Finally, the need to assess the quality of the disorder is  
highlighted, which is established through the  
description of a domain of traits, that is, those  
dimensions of the personality that stand out most in the  
individual (Figueroa, 2018).  
As for Antisocial Personality Disorder (APD), its  
main characteristic is a persistent pattern of indifference  
and violation of the rights of others, which begins in  
childhood or early adolescence and continues into  
adulthood. This pattern has been commonly referred to  
as psychopathy, sociopathy, or antisocial personality  
disorder (López, 2013).  
For an individual to receive this diagnosis, certain  
considerations must be met: they must be at least 18  
years old; they must have had a history of behavioral  
disturbances before turning 15, and these transgressions  
must not be associated with age-appropriate norms.  
Other characteristics of this disorder include aggression  
toward other people or animals, destruction of property,  
deception or theft, or violation of rules characterized by  
impulsivity and lack of remorse, according to the DSM-  
5TR diagnostic manual (APA, 2019).  
(
Chirino & Giménez, 2018). Personality disorders are  
stable phenomena over time, occurring from  
adolescence or early adulthood of a subject, being  
inflexible and manifesting in all spheres of life, causing  
clinically significant discomfort in the functionality of  
people.  
Despite being a known disorder with an established  
assessment and diagnosis, the etiology of Antisocial  
1The American Psychiatric Society in the third edition of the  
Diagnostic and Statistical Manual of Mental Disorders (DSM)  
changed the term “psychopath” to “Antisocial Personality  
Disorder” and in the fourth edition to “Antisocial Personality  
Disorder”. However, several authors establish differences  
between psychopathy (personality traits, heritable, deviant  
behaviors) and Antisocial Personality Disorder (criminal  
behaviors, antisocial). While there are other studies that  
statistically identify  
a positive correlation between  
psychopathic traits with ASPD (DeLisi, 2023). Many non-  
psychopathic criminals may have a diagnosis of ASPD (Aluja,  
1991), in addition, the literature shows that approximately  
only one third of people with ASPD are diagnosed with  
psychopathy (Salvador et al., 2015). Therefore, the present  
review includes research that addresses the legal liability of  
psychopathic traits in addition to those related to ASPD.

Personality Disorder is not fully understood. Evidence  
indicates the existence of a biological component, that  
is, heritability in its onset (Shin-Yee, 2023). In addition,  
genetic factors (MAOA gene) and neurobiological  
factors (abnormalities in the orbitofrontal and anterior  
temporal cortex) are known to be associated with the  
development of this disorder (Frazzetto et al, 2007).  
In addition to the existence of genetic indicators, it  
is considered to be a multifactorial construct, in which  
the environment in which the individual develops  
intervenes. Within this category, it is necessary to  
consider that adverse childhood experiences,  
understood as various forms of abuse, neglect, and other  
forms of childhood adversity, are related to mental  
health alterations throughout development, including  
psychiatric and personality disorders (Alvela et al.,  
ruled out when diagnosing ASPD, because antisocial  
behaviors can be better explained by the influence of  
substance use.  
Another disorder that shares certain characteristics  
with ASPD is Borderline Personality Disorder, which is  
even categorized as a personality disorder, and is similar  
in the impulsive and manipulative nature of its behavior.  
However, those diagnosed with this disorder use this  
type of behavior as a means to obtain validation and  
affection, while in ASPD individuals seek to obtain  
pleasure in transgressing social norms (Fisher & Hany,  
2019).  
In the legal field, in the past only  
psychopathologies such as schizophrenia (and other  
psychosis spectrum disorders), intellectual disability,  
and certain mood disorders were considered as  
categories subject to non-imputability, without taking  
into account personality disorders alone. In more recent  
years, the idea of mental illness has spread, under the  
consideration that personality disorders constitute a  
sufficient cause to consider a significant alteration of the  
capacity of an individual to understand and discern the  
consequences of their actions, provided that these  
alterations show a degree of consistency, relevance,  
severity or intensity to affect said faculties,  
differentiating this symptomatology from other types of  
anomalies or emotional and passionate states (Oranges,  
2018).  
Currently, it is widely believed that a mere  
diagnosis of ASPD and psychopathy is not sufficient to  
exempt one from criminal liability. These  
psychopathologies also require that they generate one of  
the following psychological effects: a) a lack of  
understanding of the illegality of the act and b) a lack of  
action in accordance with that understanding (González,  
1997). Since these disorders do not affect the  
“understanding of illegality”, they can only cause the  
second psychological effect: a lack of action in  
accordance with that understanding.  
This effect, closely related to the will, can vary in  
intensity, and depending on the degree of affectation of  
the will, it can give rise to a complete, incomplete or  
mitigating exonerating circumstance (Roxin, 1981).  
According to the “theory of responsibility for the  
result”, a subject is considered responsible for the act  
committed due to the occurrence of the result (Jiménez,  
1976).

019).  
People diagnosed with ASPD have not only been  
exposed to a greater number of adverse experiences  
during their childhood, but the accumulation of these  
experiences contributes to the emergence of more  
serious, violent and chronic manifestations of criminal  
behavior (Cáseres-Serrano & López-Robledo, 2018).  
The influence of family economic status on  
children's antisocial behavior has been shown to be a  
low-relevance predictor, in contrast to the significant  
influence of negative family characteristics such as  
neglect, hostility, indifference, and physical abuse. In  
environments characterized by these family dynamics,  
children tend to internalize a view of the world as cold,  
inhospitable, and punitive, which shapes their  
perception of life as a struggle for survival and control  
of the environment. In addition, the lack of  
opportunities to learn socially appropriate behaviors  
adds to the challenges faced by this population (Sue et  
al., 2010).  
On the other hand, another factor that seems to be  
involved in the etiology of ASPD is the presence of  
psychopathology in childhood, such as Oppositional  
Defiant Disorder and Conduct Disorder. Several authors  
consider that the symptomatology of these disorders  
acts as a prodromal factor of the diagnostic  
characteristics of ASPD (DeLisi et al., 2019).  
It is important to clarify that the diagnostic  
characteristics associated with Antisocial Personality  
Disorder may share similarities with other disorders,  
which is why the importance of an adequate differential  
diagnosis is highlighted. It is possible to establish this  
differentiation with Narcissistic Personality Disorder,  
which shares the characteristic of manifestations of  
explosive and ruthless behavior, but differs from ASPD  
in the fact that it does not present aggression and deceit  
In relation to similar research carried out recently,  
Orenes (2020) stands out, who carried out a systematic  
review of the bibliographic evidence on the application  
of psychiatric expert evidence as a tool for the diagnosis  
of different psychiatric pathologies and its consequent  
application of the legal concept of imputability. This  
research revealed that, in the case of Borderline  
Personality Disorder, in many cases the imputability of  
the defendants was completely annulled, since it was  
(
Serra, 2016).  
Likewise, Substance Use Disorder is similar in the  
impulsivity and irresponsibility component (Santos-de  
Pascual et al., 2020). In this case, consumption must be

considered that this disorder constitutes an alteration of  
cognition and will, in addition to the perception of the  
reality of the subjects. On the other hand, no reduction  
of imputability was applied in the case of Antisocial  
Personality Disorder, since it was considered that these  
individuals are fully aware of reality and act of their  
own free will.  
On the other hand, Manunza & Giampaolo (2018)  
examined the legal consequences applied to a sample of  
offenders associated with the crime of harassment,  
among which were people with pathological personality  
traits. This study showed that the presence of these traits  
is associated with repetitive and persistent harassment  
behaviors. However, it is concluded that it is the  
interaction of several psychopathological aspects  
among which are personality alterations, which  
determine a specific behavior, and that these must be  
present in a high degree of severity for it to be referred  
to as mental insanity, which can reduce or exclude an  
individual's competence to commit a crime.  
Disorder” were used, separated by the Boolean  
operators AND and OR to find these terms in the titles,  
abstracts or keywords of the studies, prior to the  
screening process based on the inclusion and exclusion  
criteria.  
The academic databases in which this review  
was carried out were Web of Science, Scopus, Medline,  
Pubmed, Social Science Database, Psychology  
Database, Science Direct and Dialnet.  
The search criteria used in this review were the  
following:  
- Inclusion criteria: Scientific articles published in  
journals with a peer review process; Scientific articles  
written in English and Spanish; Scientific articles  
located in the databases described previously;  
Scientific articles that match the search terms;  
Scientific articles published in the period 2018 - 2024.  
- Exclusion criteria: Books; Undergraduate, Master's or  
PhD theses; Dissertations; Book chapters; Incomplete  
texts.  
In short, the relationship between TPA,  
accountability and legal responsibility is a matter of  
debate. Due to the high prevalence of this disorder in the  
prison population, considering it as a cause of non-  
accountability would complicate the prosecution and  
prevention of crime. Some positions see TPA as an  
attenuating factor of mental responsibility, while others  
maintain that people with this disorder are aware of their  
actions and have full connection with reality when  
committing crimes. The dangerousness and moral  
disorder associated with TPA could justify not reducing  
accountability in these cases. (Borbón, 2021).  
The screening and selection process of the  
scientific articles was carried out using the Rayyan tool  
(Ouzzani et al., 2016), which allows the organization of  
documents extracted from the different academic  
databases selected, and the review of the relevance of  
the studies and their compliance with the inclusion  
criteria. Subsequently, a process of reading, analysis  
and synthesis of the selected studies was carried out in  
order to obtain information concerning the objective of  
the research.  
In this sense, the present article aims to carry out a  
systematized review of the legal responsibility  
attributed to subjects diagnosed with Antisocial  
Personality Disorder in the period 2018 - 2024.  
Addressing this problem from the framework of Legal  
Psychology allows us to obtain an updated overview of  
what the theory establishes about the characteristics of  
this disorder, its relationship with criminal behavior and  
the legal responsibility of those who meet its diagnostic  
characteristics.  
RESULTS  
This study aimed to examine the recent  
literature regarding the legal treatment of Antisocial  
Personality Disorder. Below are the general results of

criteria, obtaining a total of 13 articles. The selected  
studies were published between 2018 and 2023,  
reflecting an updated state of the art regarding the  
debate on the legal responsibility of subjects diagnosed  
with TPA and the need to further research on this topic.  
The selected scientific articles present relevant  
advances in topics such as the contribution of  
neuroscience to the study of individuals diagnosed with  
APD, jurisprudence regarding its treatment, and the  
contribution of psychology from a theoretical point of  
view and as a basis for legal decision-making. Table 2

to the areas described above.  
who enjoy committing illegal acts. This last  
characteristic is key to determining the imputability of  
an individual, as it indicates a cognitive capacity  
preserved during the illegal conduct (Castillo, 2019).  
The psychological approach allows a more nuanced  
assessment of legal responsibility, differentiating  
between different criminal profiles.  
Studies of brain abnormalities do not provide  
conclusive evidence of  
a medically significant  
impairment that invalidates cognitive abilities in people  
diagnosed with APD (Borbón, 2019). Some argue that  
considering the neurobiological alterations of APD as a  
cause of non-imputability is reductionist. A correlation  
is required between antisocial behavior and an inability  
to rationalize conduct, manifested in various contexts of  
the subject's life. Thus, a subject cannot be considered  
non-imputable if he has a "degree of awareness" of his  
actions and their illegality (Jurako & Malatesti, 2018).  
Functional models have been proposed to explain  
the signs and symptoms of these disorders. The  
neuromoral theory of antisocial behavior proposes that  
dysfunction of neural networks underlying moral  
behavior is a fundamental cause of this phenomenon.  
This dysfunction results in emotional, thought, and  
behavioral alterations, facilitating the development of  
antisocial behavior (Raine, 2019).

However, for these factors to be considered in the  
imputability, brain impairment must be demonstrated.  
In addition, although the theory suggests a volitional  
alteration due to the involvement of specific areas of the  
brain, it must be specifically considered and assessed  
whether the subject had full knowledge of his actions  
and their consequences. This approach poses a  
significant challenge in legal practice, given that the  
precise assessment of brain impairment and its impact  
on the moral behavior of the individual is not a simple  
task (Raine, 2019).  
Furthermore, psychopathy can hardly be  
considered a unitary phenomenon, with a single cause  
and homogeneous manifestation, according to its  
multidimensional structure. For example, reduced  
sensitivity to emotional stimuli and aversion to threat  
signals in psychopaths explains their lack of intrinsic  
motivation towards the well-being of others and their  
lack of empathy. These individuals also show a deficit  
in the regulation of decision-making, possibly caused by  
atypical connectivity in cortical areas (Decety, 2020).  
Similarly, some approaches consider psychopathy  
as an adaptive response to adverse environments.  
Empirical evidence is not sufficient to consider  
psychopathic learning abnormalities as manifestations  
of disabilities due to internal or neuroanatomical  
impairments. For this reason, a social intervention  
approach is proposed to mitigate the negative effects of  
psychopathy, suggesting that societies could benefit  
from adjusting the physical and social environments

DISCUSSION  
Understanding the unlawful nature of an act and  
the ability to act on that understanding at the time of the  
crime are crucial to determining legal liability.  
Personality disorders, including ASPD, and  
psychopathy vary in intensity and severity from one  
individual to another. Likewise, the diagnostic criteria  
and symptoms of ASPD and psychopathy do not  
guarantee a total loss of the ability to understand the  
unlawful nature of actions. Therefore, the diagnosis of  
these psychopathologies does not automatically imply a  
reduction in sentence; an analysis of the circumstances  
of the crime is required to determine the extent of the  
impairment in the ability to understand the unlawfulness  
of the conduct (Borbón, 2019).  
Currently, there is little consensus on whether APD  
and psychopathy should be considered as grounds for  
non-imputability. Legal decisions must be based on the  
personal variables of each case and on the conceptual  
difference in the capacity for guilt between law and  
neuroscience (Harbottle, 2019). This lack of consensus  
reflects the complexity of integrating neuroscientific  
knowledge into the legal field, where imputability must  
be assessed in a multidimensional manner.  
In this sense, psychology has a direct impact on  
criminal law by providing useful technical knowledge  
to distinguish between common criminals and those

https://www.sa-rj.net/index.php/sarj/article/view/48  
that exacerbate these traits (Jurjako et al., 2021). This  
adaptive approach offers a broader perspective to  
understand and manage these disorders in legal  
contexts.  
clinical categories, the nature of these disorders is  
heterogeneous, and offers little prospect for integration  
with neuropsychological data to yield definitive  
conclusions on criminal responsibility. Second, these  
categories were not created to differentiate between  
criminally responsible antisocial individuals (Jurjako et  
al., 2023).  
Ultimately, to the extent that psychopathy or ASPD  
does not impair an individual’s volitional capacities,  
i.e., their ability to control their behavior, they will not  
be excused from culpability for criminal acts.  
Psychopathy is also not generally accompanied by  
delusions of the kind that would deprive the affected  
person of the ability to understand the nature of their act.  
Whether it would prevent them from “knowing that the  
act or omission was morally wrong” is a considerably  
more controversial question, one that continues to  
divide opinions among psychologists, lawyers, and  
philosophers. Finally, not only can psychopathy and  
ASPD be rejected as exonerating or mitigating  
conditions, they may even serve as aggravating factors  
in sentencing (Malatesi et al., 2022).  
On the other hand, studies on gender differences  
and forms of manifestation of ASPD and psychopathy  
show that ASPD is less prevalent in women compared  
to men. Likewise, women with high scores in  
psychopathy tend to commit mostly impulsive crimes,  
and have a higher incidence of personality disorders,  
especially histrionic and borderline. On the other hand,  
psychopathic traits in women with zero, partial or total  
responsibility are similar, and psychopathy has been  
seen to be more associated with personality disorders  
than with psychotic or schizophrenia spectrum disorders  
(
Carabellese et al., 2019).  
In relation to incidence, in the United States,  
approximately one-third of the male prison population  
sentenced for homicide has been classified as  
psychopathic. Linked to this, the positive correlation  
found between psychopathy scores and the ASPD (ρ =  
0
.72) is interesting, in terms of criterion validity.  
Furthermore, psychopathy is frequently cited during  
capital sentencing proceedings (DeLisi, 2023). This  
high prevalence and the use of psychopathy in  
sentencing proceedings reflect the importance of this  
disorder in the penal system.  
An analysis of sentences carried out by Álvarez et  
al. (2019) shows that the majority of defendants do not  
present impairments in their intellectual and volitional  
capacities. Thus, subjects with TPA without  
comorbidity with other pathologies are not considered  
unaccountable. Those to whom exemptions or  
alternative measures were applied suffered from  
disorders in addition to TPA. This shows the need to  
consider comorbidity and other contextual factors when  
evaluating imputability.  
In any case, TPA and psychopathy are especially  
prevalent in the prison population, which is an  
indication of non-causality to reduce their legal  
responsibility (Fernández, 2020). Expert evidence is a  
judicial method to adequately assess the acts committed  
and the possible reduction of imputability based on the  
diagnosis of psychiatric disorders. Since TPA is  
frequently related to criminal behavior and is  
characterized by an inability to adapt to norms and  
display violent behavior, the possibility of reducing  
imputability is limited.  
CONCLUSIONS  
The determination of legal responsibility depends  
crucially on the ability to understand the wrongfulness  
of one's actions and act accordingly. Although the  
presentation of ASPD and psychopathy can vary in  
intensity and severity, their diagnosis does not  
automatically imply an inability to understand the  
wrongfulness of one's actions. Studies of brain  
abnormalities in individuals with ASPD do not provide  
conclusive evidence of significant impairment that  
negates their cognitive abilities. Therefore, it is  
necessary to evaluate the specific circumstances of the  
crime to determine how these conditions affect the  
mental faculties of the accused.  
The debate over whether ASPD and psychopathy  
should be considered grounds for non-imputability  
remains unresolved, highlighting the complexity of  
integrating  
neuroscientific  
and  
psychological  
knowledge in the legal field, where imputability  
requires a multifaceted assessment. Legal provisions  
and sentencing analyses tend to recognize the legal  
responsibility of defendants with ASPD due to the  
clinical particularities of the disorder and the absence of  
Legal provisions, such as the Orlando reform, tend  
to recognize the chargeability of defendants with APD  
due to their tendency to commit violent acts without an  
admission of guilt (Oranges, 2018). This underlines the  
need for an individualized assessment of each case,  
considering both clinical and legal aspects.  
recognition of  
guilt.  
Ultimately,  
if  
these  
psychopathologies do not significantly affect volitional  
and cognitive capacities, they do not absolve individuals  
of guilt, and in some cases, they may aggravate the  
sentence.  
The debate on the imputability of psychopathy and  
ASPD seems to have reached a stalemate. First, as
