The ownership of "I made a mistake" (you noted responsibility) is important. I feel strongly in the value of accountability, not in a blame or even necessarily consequences sense but in an integrity and character sense. The way you phrased it there is important. You noted this and other aspects, but that part struck me.

Also: a forgiveness button. I sometimes feel like society has forgotten forgiveness: we seek revenge and punishment more than redemption and growth. So your Forgive button: I love it.
