Genocide

Why does Genocide happen? There are probably a lot of answers. None that make any sense... But to me i think Genocide happens because of crazy people trying to gain power. Think about it there one man that wants to rule a large area. He could work hard to have every love him and such, or he could kill a bunch of people and have people terrified of him. A lot of leaders would say they would rather have there people be scared of them instead of love them.
