These people are just plain mean, they're out for themselves. They'll lie to your face as well as just bitch you out, even though you're "best friends" Eventually the relationship will end because he/she has decided they don't want to be around you anymore, and will come up with a twisted version of the truth (possibly not even based on truth) and tell everyone, turning you into either the dick/bitch in the situation or completely embarrassing you. Either way, they just love to see you upset, and don't even feel guilty.
Friend 1: "Why aren't you and so-and-so friends anymore?"

Psychotic "Friend": "Because, she is such an awful, backstabbing, lying bitch of a best friend, who told all my secrets and tried to break up my boyfriend and I."

....Later....

Friend 1: "Hey so-and-so, <insert psychopath friend's name here> said you're a bitch. I've been thinking, and she's so right. She's so much better than you, I think it's best we not be friends anymore. Ta."

So-and-so: "...................sorry?"

similar to sociopath/antisocial personality but less emphasis on conning, manipulation and more on antisocial behaviors and often displaying the following traits

1...... extremely volatile personality with a long violent history and lack of regard for others. although sociopaths can be violent and often mad when their expectations are not met, psychopaths are more intrinsically violent
2..... impulsive and wreckless antisocial behaviors (ex: forcible rape, violent kidnappings and robberies, dangerous behaviors.
3..... dangerous behaviors stemming from a combination of personality disorders and mental illnesses yielding ane extremely dangerous type of offender
4..... MOST IMPORTANTLY: PREDATORY BEHAVIOR. The psychopath will enjoy hurting and killing others, they may even recieve sexual gratificaiton from such behaviors. They will often PREY ON OTHERS and never feel attached to others or bond to people.
saddam hussein, adolph hitler, ted bundy, mao, joseph stalin, osama bin laden, henry louis wallace (serial killer from charlotte), BTK, jason voorhees, wade in river wild (kevin bacon), the guys in last house on the left and MANY dangerous people are all psychopaths
