I thought a psychopath was dangerously crazy while a sociopath just doesn't like people. It looks like I picked a bad day to practice medicine.
I'm not a doctor either, but that is the basic definition.
That is my understanding as well. A psychopath is a highly disordered sociopath. Bundy was a psychopath while Stalin was a sociopath.
In hindsight the psychopath's behavior looks crazy and has strong psychosexual elements to it while sociopath's behavior looks ruthlessly opportunistic and exploitative. Compare Ted Bundy to Jeffery Skilling. Skilling was Id'ed as a sociopathic by his own classmates at HGSB during ethics case studies. Skilling, normally a brilliant student, was baffled by the very moral principles the cases represented.
That would be a misanthrope or in modern terms, a folksaphobe.
