Sociopath

A sociopath is an individual who suffers from a mental disorder known as Antisocial Personality Disorder (ASPD). People who suffer from Antisocial Personality Disorder demonstrate a pervasive disregard for the laws of civilized society as well as the rights of others. It is a form of psychopathy, but does not necessarily include the violent and compulsive tendencies associated with other forms of psychosis. A sociopath is born out of conditions of his or her environment, whereas the conditions that creates a psychopath are often hereditary. The development of socipathy often begins during childhood and continues to develop into adulthood.

In terms of television entertainment, sociopaths are often found in crime dramas and horror programs. Though they are generally presented as antagonists, some shows have also developed their central protagonists as sociopaths such as CBI consultant Patrick Jane on the popular CBS series The Mentalist.
