How can i satisfy my sadistic needs?

I'm glad your looking for ways, to not hurt people, try writing your thoughts down, or making a story. You could also start taking boxing in school, or football, some kind of contact sport that you can't get in trouble for. I used to go outside and peel the bark off tree's ( I know I was weird then ) but it helped. Read a book about people who get tortured, I hope this helps. ^.^
