What's wrong with people?

I think people who hurt animals are sick. Why harm something that can't defend itself?
Joanne Cole, who lives in Tunstall in Stoke-on-Trent recently had to have her cat's leg amputated because some careless idiot shot it in the leg with an air riffle. It was also reported in the news not long ago about teenagers who repeatedly threw a cat of the top of a multi storey building until it eventually died! People who harm things that can't defend themselves should be severely punished!!!!!
