I know its not normal that i dont care about the deaths of others?

I know its not normal that i don't care at all about anyone who died in the holocaust, any war, or any tragic event. I understand that dying is bad but as long as its not me i seriously don't care. And honestly if i could get a lot of money but a lot of people died for it i wouldn't care, as long as i didn't have to kill them. Its not that i couldn't kill them but killing someone isn't worth the effort or the money. I daydream of beating people up all the time, and i actually kind of get excited from it. But i would never hurt any close to me, or anyone at all. Yet again its not that i couldn't its just that i don't feel like it. If some got me mad enough or stole something VERY precious to me i would kill them. This doesn't effect my life that much, people just think I'm weird. I have a few friends, and lately have been trying to gain more, but no one knows how i feel. Is their any advice anyone can give me on how to go about dealing with this. I could go on but this is my first post and i don't know how long i should make my post.
