If you suffer from rumination or can’t get over regrets I think your worst sin might be pride because to be stuck in regret is to think that you had full control over that past situation instead of thinking maybe you were never as powerful or intelligent or wise as you believed

Self-forgiveness and agency are intimately linked. Without ample compassion, the threat of failure becomes too terrifying. When you're irrationally afraid of judgment, you can't shoulder full responsibility, so you can't inhabit your full potential & wield your power wisely.
