If a person is aware that they have "wronged" (for the sake of avoiding the word sinned), taking some sort of action to fix things and get rid of the guilt is what's needed for the sake of that individual's mental health. If a person lives with a feeling of guilt and remorse that already is HELL to me.
Is it fair? Fairness is a subjective topic. I personally don't feel it's fair or very intelligent of me to have wasted my energy and passion into believing and supporting a God who would be so unreasonable and unrelenting.
