Understanding personal capacities for evil leads to moral development.

Evidence

Each human being has an immense capacity for evil. Each human being understands, a priori, perhaps not what is good, but certainly what is not. And if there is something that is not good, then there is something that is good. If the worst sin is the torment of others, merely for the sake of the suffering produced—then the good is whatever is diametrically opposed to that. — Jordan B. Peterson, 12 Rules for Life An Antidote to Chaos, 600
