And you have to play medium to long-term stable, voluntary games with other people. And that's hard. Nothing but diligent, upward-oriented work over the years puts you in that position. Whereas if you make an unwarranted moral claim, “I'm compassionate”, then, instantly, you're with the angels. And it also allows you to derogate those who you regard as predatory and also enhances your moral virtue.
“Not only am I compassionate, and that makes me good, but and I'm on the side of the angels, but there are the snakes, and they're not in me at all because I'm saintly in all regards”. The snakes have to be somewhere. And the most convenient place to put them is in someone else. That's how "cancel culture" works, by arrogantly and narcissistically discrediting others with different opinions and without putting weight on any logical reason.
