Answer:
1. Psychopathic qualities, like other personality traits, are heavily impacted by heredity, while research suggests that non-genetic variables play a role as well. In patients with psychopathic tendencies, scientists have noticed indicators of aberrant functioning of specific brain areas (such as the amygdala).
2. Antisocial personality disorder has no recognized cause. Environmental and genetic variables, such as child abuse, are thought to have a role in the development of this illness. People who have an antisocial or alcoholic parent are more vulnerable. Men are impacted in far greater numbers than women.
