" Psychopaths are generally viewed as aggressive, insensitive, charismatic, irresponsible, intelligent, dangerous, hedonistic, narcissistic and antisocial. These are persons who can masterfully explain another person's problems and what must be done to overcome them, but who appear to have little or no insight into their own lives or how to correct their own problems. Those psychopaths who can articulate solutions for their own personal problems usually fail to follow them through. Psychopaths are perceived as exceptional manipulators capable of feigning emotions in order to carry out their personal agendas. Without remorse for the plight of their victims, they are adept at rationalization, projection, and other psychological defense mechanisms. The veneer of stability, friendliness, and normality belies a deeply disturbed personality. Outwardly there appears to be nothing abnormal about their personalities, even their behavior. They are careful to maintain social distance and share intimacy only with those whom they can psychologically control. They are noted for their inability to maintain long-term commitments to people or programs. "
