It's not that black and white, little man. Each person is different, each experience which makes them more or less receptive depending on what was done, the reason. Some wrongs? They can't be forgiven by the people who suffered them. That doesn't mean that people aren't allowed redemption, it just means that some wrongs hurt too much for those who felt them to just let it go.
It takes more than words to prove a point. It takes time.
