A lot of wisdom in Grishka's last response.

Forgiveness is a choice.......and when we make that choice it can really lighten our burden. But if we do it out of 'obligation'....and, as Eliza says, have to 'conjure up somehow a good feeling about the sinner', then it's probably not going to work the way we want it to.

I'm a great admirer of "Restorative Justice" concepts and practices.   I've witnessed many people relieve their burden by forgiving people who have perpetrated the most heinous crimes upon them.

I've also witnessed those who haven't decided to do that.........but have still stayed 'in touch' with those angry feelings and strong judgments, and have used them in a way that has helped them move on rather than remain stuck.

Either choice requires courage.   I would never stand in judgment of anybody who makes any choice that 'works' for them........and is also creating more good than harm to society.
