People hurt others. It's called life. I have an extensive abuse history myself, I have experienced and also witnessed some of the worst that people can do. I have two sisters that were also badly abused, they most definitely have emotional issues because of it. But in time they've both been learning in their own ways that they can still feel love for the people that harmed them, life isn't black and white. You can hate what someone's done, or even their personality, and still love them it appears though it seems to be uncommon as most people who have been abused end up seeing the world in very black and white terms.

What simplifies things for me is that I am incapable of love, so I'm just indifferent towards my abusers. Though mind you I had my fun with them for being assholes when I was teenager, heheheh oh the joys of being young.
