Oh, one more thing... Here's a wikipedia definition of SOCIOPATH. Sound familiar?
Sociopathy/Psychopathy:
Lack of a conscience in conjunction with a weak ability to defer gratification and/or control aggressive desires, often leads to antisocial behaviors. Psychopathy does not necessarily lead itself to criminal and violent behavior. Instead, psychopaths high in social cognition may be able to redirect their antisocial desires in a different, non-criminal manner.[citation needed]
Psychopaths (and others on the pathological narcissism scale) low in social cognition are more prone to violence against others, failure in occupational settings, and problems maintaining relationships. All psychopaths differ in their impulse control abilities, and overall desires. Psychopaths high in the pathological narcissism scale are more equipped to succeed, but pathological narcissism does not in any way guarantee success.
