You will receive what you want your enemies to receive.
If you look at it from this point of view:
What your enemies receive is not going to affect you one way or the other, so you might as well wish for them to be happy.
Forgiveness is a gift you give yourself. Do not exchange forgiveness with forgetfulness, you should want them to be happy, however, it’s not your job to make them happy. That’s their responsibility.
