I think the point which impressed me most in Janie's post, were the words, "when one is able to do so". I know for a certainty that there are some things which I could never forgive, but accept that bearing a grudge is destructive in some ways.

I think it is possible to be too forgiving, I think perhaps our society is becoming brainwashed, our sympathy for wrongdoers of all descriptions, seems to outweigh our compassion for the victims of their evil deeds.
We have lost our moral compass.
