Antisocial personality disorder (APD or ASPD) is a psychiatric diagnosis that interprets antisocial and impulsive behaviors as symptoms of a personality disorder. Psychiatry defines only pathological antisocial behavior; it does not address potential benefits of positive antisocial behavior or define the meaning of 'social' in contrast to 'antisocial'.
Central to understanding individuals diagnosed with antisocial personality disorder is that they appear to experience a limited range of human emotions; however this should be regarded critically due to current lack of exploring emotional response in detail even in animals. This can explain the lack of empathy for the suffering of others, since they cannot experience emotion associated with either empathy or suffering. Risk-seeking behavior and substance abuse may be attempts to escape feeling empty or emotionally void. The rage exhibited by psychopaths and the anxiety associated with certain types of antisocial personality disorder may represent the limit of emotion experienced, or there may be physiological responses without analogy to emotion experienced by others. - (Wikipedia, emphasis mine.)
