The question of whether psychopaths are criminally and morally responsible has generated significant controversy in the literature. In this paper, we discuss what relevance a psychopathy diagnosis has for criminal responsibility. It has been argued that figuring out whether psychopathy is a mental illness is of fundamental importance, because it is a precondition for psychopaths’ eligibility to be excused via the legal insanity defense. But even if psychopathy counts as a mental illness, this alone is not sufficient to show the (...) insanity defense is applicable; it must also be shown that, as a result of the illness, specific deficits in moral understanding or control are present. In this paper, we show that a diagnosis of psychopathy will generally not indicate that a defendant is eligible for an insanity defense. This is because the group of individuals subsumed under the diagnosis is so heterogeneous that while some psychopaths do show significant impairments in affect and control which may impact on their responsibility, many psychopaths are not incapacitated in a way relevant to responsibility.

Psychopathy is typically characterized as a constellation of deviant personality traits and behavioral tendencies. The link between psychopathic personality traits and pervasive antisocial behavior raises a crucial question concerning the legal accountability of offenders with psychopathy. Some argue that the unique clinical profile and neurobiological peculiarities of individuals with psychopathy mitigate their responsibility, while others maintain that current scientific knowledge does not support the use of psychopathy as an exculpatory condition for criminal offending. Our overview mainly centeres on whether offenders (...) with psychopathy can be considered legally insane. In this regard, our overview suggests that there is still an ongoing debate whether psychopathy should be used as a legally relevant construct for determining criminal responsibility. Moreover, our discussion indicates that careful attention should be put on empirical and conceptual issues surrounding the role of (neuro)scientific data for determining whether individuals with psychopathy should be considered criminally blameworthy for their wrongdoings.
