Is it normal to want to hurt, maim or kill some random person?
I occasionally get the urge to severely harm some random person, for no reason (although this feeling is heightened when I'm stressed). On the basis of semi-personal information, I think that I am a schizoid/sociopath. I am not saying that these to things are synonymous with each other, rather that I demonstrate a variety of symptoms for both.
Back to killing, I am usually content with simply observing people, or, at the very lease, daydreaming about torturing someone. And I don't really think that I am that bad of a person. I mean, if you ask anyone who knows me, they'd probably say that I am a sweet person who would never hurt anyone. Haha. And I haven't actually hurt anyone (in real life at lease), but that's not to say that, if given't the opportunity, I wouldn't cause someone some very serious and permanent damage. Not just yet. ;)
