Cool.
How about you answer your first question...
Oh, you're "minoring" in psychology, and wish to enlist the help of "real" psychopaths to get your paper done? Well, here's a bit of advice for you, served up in signature sociopathic style~
Your question belies your lack of understanding of psychopathy as a psychological contruct. Did you even bother to conduct a modicum of research on the subject prior to posting here? I don't think so. Otherwise, you might not have asked such an inane, irrelevant question- in which you even misspelled the object of your misinformed query. (It's homicidal, Einstein)
To wit, what do you mean by "If younger than 10 was it sexual, homicidal, etc?" Are you asking us whether we suspected ourselves of being psychosexually deviant monsters, and blossoming axe murderers, prior to the tender age of ten? In response, let me ask you this: did you* know that you would grow up to be an intellectually stunted douchebag at such a critical stage of your psychological development?
You might want to start by looking up the pcl-r, and familiarizing yourself with the diagnostic criteria of psychopathy, before making your fumbling attempts to interview some "real live specimens" with which to try to impress your professors. And I have to be frank: things aren't looking very bright for you, in terms of a promising academic future. You might want to pick up a trade, or something. It sounds like you're going to need something to fall back on. :p
