Psychopath

A psychopath is someone who suffers from psychopathy. Psychopathy is a personality disorder characterized by an abnormal lack of empathy combined with strongly amoral conduct, masked by an ability to appear outwardly normal. Neither psychopathy, nor the similar concept of sociopathy, are nowadays defined in international diagnostic manuals, which instead describe a category of antisocial/dissocial personality disorder.

If ever there is a situation where one can get two or more psychopaths to work in tandem, then rest assured... a fun time will be had by all. Such was the case when the demonic dream entity Freddy Krueger needed some help in getting the people of Springwood, Ohio to remember him again, thus restoring his lost power. To this end, he resurrected Jason Voorhees from Hell and sent him on a killing spree, to elevate communal fear, and thereby empowering Freddy.
