What is forgiveness to you?

To a lot of people, forgiveness comes when the person who did wrong feels regret over their actions. Not regret for the consequences, but regret for the harm that their actions caused.

Tbh, if someone is hoping that just paying false lip service will guarantee then forgiveness from an all knowing being, I'll wonder what exactly it is that they believe. An all knowing God would know whether you actually regret harming someone, or if you just regret not getting into heaven. Is there any chance you could explain that to me? I have seriously never understood why some religious people believe that they could fool an all knowing God.

If that amount of sin is forgiven easily, I would argue that many of the harmless actions that current organized reliegon is against would also be forgiven.
