You start off the monster. Humility is learned when you fall in some way - ego death. Without that event, no humility is learned. But people trick themselves into believing they're good - if they emulate the right people, who are usually authority figures, then they think they must be good. That's just a copy, and usually a copy of a copy of a copy etc. To learn humility, they would have to it from the source, which is a hard knock. Thus, the people who wear their goodness like a garment are, in fact, the most monstrous. If they were good, then they wouldn't need the garment, and then the good appear to be evil to the evil ones, who put so much effort into the appearance of goodness. That's why the most pious people are the most hateful, and the people highest in authority are the furthest from the good. That's the trend, at least.
