A charismatic leader gets people to join their movement with vague notions of "freedom" and "tyranny of the state", empowering these people, which just turns them into the worst versions of themselves, becoming the very tyrants and pain givers they claim to want to stop. When their motives are found out, at first it seems for reasons that you can be sympathetic for, but end up being completely selfish and self-serving and kind of stupid. The leader themselves seem to make some good points, only to also be completely self-serving and selfish, and even a little bit stupid and unhinged, even comically so, if there wasn't a very real danger of innocent people getting hurt. They simply want to do whatever they please without consequences.

...yes. What a completely unbelievable, ridiculous plot. This could never, ever happen.
