Forgiveness goes two ways. I've forgiven nearly everyone who has hurt me, knowing they did the best they could, and were in a tough space at the time. (ok there are a few lingerers, working on it)...
I'd rather see personal breakthrough in someone who has had a rough time of it, and have grown past their hurt & pain.
The past is the past.
How wonderful is it to see peace and joy in someone who has overcome?
