I'll be honest, the post originally came off as fluffy, though not enough to say anything about it, but your comment made me reread it.

I really don't think you guys disagree that much. You're talking about different perspectives (not behind yourself vs not behind others) and a different focus (you on regret, him on forgiveness). Otherwise you both have some great wisdom in what you've said, don't think it's necessary to put him down so thoroughly.
