Antisocial Personality Disorder

From the wiki.

Antisocial personality disorder (APD) is a mental disorder. It is defined by the American Psychiatric Association's Diagnostic and Statistical Manual: "The essential feature for the diagnosis is a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood." Deceit and manipulation are considered essential features of the disorder. Therefore, it is essential in making the diagnosis to collect material from sources other than the individual being diagnosed. Also, the individual must be age 18 or older as well as have a documented history of a conduct disorder before the age of 15. People having antisocial personality disorder are sometimes referred to as "sociopaths" and "psychopaths".

And here is a nice little bit on causes:

Glueck and Glueck (1968) saw reasons to believe that the mothers of children who developed this personality disorder usually did not discipline their children and showed little affection towards them.
