An antisocial personality disorder differs in many important ways from other psychological disorders and involves behaviors and characteristics most people would judge unfavorably from a moral perspective. However, ASPD may have a strong genetic or biological component, and therefore, the characteristic behaviors, though volitional, may not be simply a matter of free choice. Some people with antisocial personality disorder are extremely dangerous. Biological researchers increasingly identify genetic markers or mechanisms causally related to the disorder. Consider the implications of research that would demonstrate clear biological substrates to this disorder regarding moral or criminal responsibility for antisocial behaviors.

A range of possibilities can be considered, from screening all parents prenatally with this genetic marker to mandatory psychotherapy for the individual and family of a child with this genetic marker. Or should nothing be done?
