If God has forgiven all of the sins that we have made,who are you not to forgive,words has been spoken and its up to you if you are going to continue the hate.
Giving second chances to people who clearly know they're in the wrong is not why people 'forgive'. You wouldn't acquit a thief that has already stolen from many people. You wouldn't 'forgive' a ponzi operator that has already scammed twice before their most recent project.
Don't try to appeal to emotion.
