Truth. As much as I'd like to see these people have some epiphany moment of realizing how wrong they were to back people who would turn on them, they won't. They deserve the better world we want for them, even if they are too much of a cantankerous bastard to ever be thankful for it.

We need a better society that snuffs out such hateful movements before they capture vulnerable people. Because that is what these type of groups (read: cults) operate on, finding vulnerable, lonely people who need to feel like they are part of a group and need to feel like they have a purpose. They offer those things to the lost and broken, even when they know they will turn their own knives back on those they recruit, when the time comes. As we saw with COVID, even facing death won't make them learn they backed the wrong horse, with many of them saying COVID was a hoax until their own rasping, COVID-infected dying breath.

As cathartic letting those who get sucked into these cults suffer the punishment of their own hubris feels, they will learn nothing from it. Better to create a better world around their crappy selves.
