It is just a question and despite your long post you did not answer it either.
Forgiveness is not yours to grant.
If it happened while still on this planet, I would wonder out loud. Cool with you?
Regards it not being mine to give, that is precisely correct, and I have no problem not forgiving those scumbags.
Is it yours? Do you speak for all affected on this planet? Or are you some self righteous prig who is holier than others, and thinks nothing of forgiving some asshole who gloated while he looked into people's eyes he knew were going to die of his hand in a few moments?
Are you in fact that holy?
