How come there is so much violence in the world?

There really isn't that much money so people steal because they have to feed there family but there are different alternatives to making money instead of stealing. Like trying to find a job and  doing many other thing to help your family.

all because people kill people because of either what that person said to them or did to them that made want to hurt somebody of even worse kill them. People just be nice to other people and help the less unfortunate
