I believe that forgiveness is a choice, but if you are truly Christian, it is something you must do, no matter what. I think, too, that forgiveness is a part of the healing process. Hate is a poison you can't keep in your heart.
That being said, I don't know if I am that good of a person. If that were my community, my little girl, well, I don't know how I would feel. It is too far outside my mind to even comtemplate.
And other posters are also right. This guy is dead. He has to face The Maker. What is left behind are his wife and children to pick up the pieces. They can't be held responsible for his actions. They have to try and have a life now that they have been shamed and wronged by this man they trusted as a husband and a father.
That experience, too, is beyond anything I can imagine.
God bless them all.
