What is the worst thing a parent can do to their child? Why?

The worst thing a parent can do to their child is put them out. When a person has a child they have taken on the responsability of taking care of the child. This is the worst because if a parent put a child out with no were to go their not a good person. Another thing is tell your child that you don't want them and they were a mistake. That's just bad parenting to tell a young child that you don't want them. Also when a parent let their kids do what ever they want. Parents are suppose to keep their kids in check and want them to do better. All these things are very bad things that parents can do to their children but, the WORST...WORST is to beat or molest your child.
