You should pity them. They know not what they do and I can pretty much guarantee you they were victims themselves, especially as young children. Most victims of abuse, abuse others, it's just a really horrible cycle and takes a lot of hard work, therapy, faith and willingness to learn how to break the cycle which is often generations of abuse. My mother broke the cycle in her family. She's an amazingly strong woman, but I know her faith is probably what gave her the strength to do it and forgive her abusers for what they did to her.
