Merrie Haskell said this quote

Child, you do not forgive because the person who wronged deserves it.You misunderstand the point of forgiveness entirely. The only cage that a grudge creates is around the holder of that grudge. Forgiveness is not saying that the person who hurt you was right, or has earned it, or is allowed to hurt you again. All forgiveness means is that you will carry on without the burdens of rage and hatred.
