If someone is truly sorry, and does show that in a way that I can see he/she/they meant it...then I can forgive. But when "something so despicable" happens to you and the perpetrators of that crime show no repentance; I don't and I won't forgive. I've read a lot of books on forgiveness and they alway say that to hate someone hurts you more than it does them. But even though I may hate someone, I don't let it control my thinking process and try to let it go. Out of sight, out of mind. Christ wasn't too forgiving of the Pharisees, if at all.
I personally cannot forgive those that slandered my son and "marked" him without warning when he married an unbaptized publisher. They showed no remorse and took no actions to right the wrong. I don't think it makes me a bad person to be unforgiving. Sometimes you have to protect yourself from people who have no conscience.
