Is it okay for me to forgive my girlfriend for abusing animals as a child? Please, any honest answers?

Who cares if her parents were not around, my dad wasn't, but your still raised in a world of rigth and wrong and you know whats right and what's wrong. I had bitches who blaim there parents for ****. She does it because she wants to feel in control, I wouldn't forgive her for that **** since she carries on doing it, say you aint gonna be with her if she carries on doing it man.
