Psychopaths may come in two varieties

Some men and women regularly prey on the people around them. Through charm and

manipulation, they take what they want and do as they please. Even the vilest acts

leave these predators remorseless.

People with this personality, who are known to psychologists as psychopaths,

sometimes pay for their deeds by going to jail or psychiatric facilities for

criminals. In the August Journal of Abnormal Psychology, researchers report

finding that psychopaths who evade the law may constitute a breed apart from those

who at some point end up behind bars.
