The Problem with those flashbacks is that it is hard to elicit Feelings of Sympathy with it, because they are overdoing it.
Look! This Douchebag isn't actually so bad after all! He had a bad Childhood! Aren't we all just products of our Enviroment?
That line of Reasoning is not wrong, but it has to be presented in a more subtle Manner. If you have to have a flashback make it short and concise, one maybe two Pages tops would have sufficed to get the Message across.
