For some people, life has to humble them in order for them to realize the error of their ways. Even with that, some folks are a lost cause that no matter what karma comes their way, they don't or refuse to change. Some people can change their behavior, but their values remain intact. I think folks have to want change in order to really change. By wanting change, someone does the work to become a better person, which involves making amends with those you've hurt. Anybody can utter apologies, but it's a different story when you have to make amends with those you've hurt. Most people had no problems messing over folks, but when it's time to go back to them for forgiveness, some folks don't or won't do it.
