The more I read about this guy, the more he sounds like a psychopath.

I believe the correct term is 'sociopath'.

The difference between "psychopath" and "sociopath", as far as I can tell, is whether you think it's primarily caused by a mental disorder or socialization disorder. I think the evidence favors the former and the term "psychopath" has been returning to favor. You can find some good deatils here.
