It is likely that Richard has a psychopathic personality disorder. People with this disorder of the person usually show antisocial behavior, little or no empathy, social contacts only if it is considered necessary, violent and impulsive behavior and an uninhibited character. It is difficult to diagnose this disorder unless the person commits a crime because they do not usually go to receive mental health care.
