That's why I said "sometimes" and not, "every child, everywhere, all the time."

Your 23 year old may be really immature still, some kids are not. Depends on the kiddo. However, I don't think forgiving abusive parents is a lesson that should be taught. You can hold someone accountable without hating the rest of the world. I can not forgive an abusive parent and still see the good side of things without being a doormat.
