Is my friend pshyco?

Think i spelled it right..lol. Hes 21, and he says he enjoys playin San Andreas alot and has fun killing ppl. I dont know if hes crazy, but i know its a video game, but still. Then he gets mad because i dont have him on my Myspace Top Friends list, (boo hoo, its just myspace!) Has a sick sense of humor, backstabber towards everyone and is lazy.
