It's always never too late to make amends when you are still alive. There are certainly many ways where past wrongs can be righted.
I once pointed out something about an unfair performance report and was harshly berated for it. I lost a chance for a scholarship on account of it. Some years later, the person responsible for it showed up at an alumni reunion to apologize indicating that he deeply regretted his biased action. He showed me his recent action at redressing the wrong...he got it expunged from my records and sought the permission of the varsity senate to amend my grade. To accomplish this he certainly went through a lot of trouble if not grief. Though I will never ever get that scholarship again and life could have been quite different, he had done good to atone for his rashness. I have certainly forgiven him, but I will not forget his action and I will continue to watch out for people of his ilk.
