Psychology - Child abuse theories?

Beaten children very early on imilate the violence they endured, which they may glorify and apply later as parents, in believing that they deserved the punishment and were beaten out of love. They don't know that the only reason for the punishments they have ( or in retrospect, had) to endure is the fact that their parents themselves endured and learned violence without being able to question it. Later, the adults, once abused children, beat their own children and often feel grateful to their parents who mistreated them when they were small and defenseless.
