Why Why Why?

I have just read about Baby Peter, a 17 month old boy who was killed by his mother and her boyfriend in London. Yes, there are people out there who have children without realizing they need to care for them, and there are people who are too selfish and irresponsible to care for anyone other than themselves. But domestic violence is just far too common nowadays. And it is always the children, who never asked to be born and never did anything wrong, who suffer.
