Yes, I've always found that an odd tenet. Surely one who is truly repentant, without simply being scared of hell, must therefore know their sins are immoral intrinsically. That means that they committed them with the capacity to work out they were wrong (even if they didn't carry out that calculation at the time).

Someone who does not repent is someone who continues to believe they were right to do what they did.

Who has committed the worse wrong?
