The goalpost shifted. The original example was "the characters destroyed the entire village." It was not they defended themselves from a lynch mob. It was not that they killed a few an escaped. It was that they destroyed the entire village.
The original scenario was: They will arrange a lynch mob, but the players have the capability to destroy the entire village, so that would presumably be a dumb thing to try. And from there, things escalated further and further, or goalposts shifted, or whatever. Either way - if for some reason all the villagers decide to try lynching a player character for bogus reason, there might be very immediate and bad consequences for the villagers that actively threaten them, but the consequences for the player characters would be much more removed - simply because the investigation into what happened at the village takes time and if there were plenty of resources to investigate, identify and persecute them, and if it was a guaranteed or highly likely outcome, it seems the place doesn't need adventurers.
Unless the investigators are adventurers themselves. Which could be fun. But since the village-burning isn't, we'll probably need something else to create this scenario. Like a village burning down after the adventurers visited, by some nasty villains something. I don't think I'd be okay with my players killing a village and that would be a reason to talk about the nature of our shared game experience out-of-game, not talking about in-game consequences, but then, my villagers probably also won't form suicidal lynch mobs.
It reminds me of something - in the real world, people might have killed women for being suspected being a witch - but in the real world, witches don't exist. If a bunch of villagers decide a random women in town is a witch, they are just going after a lone woman. She has basically no chance. If there were actual witches, they'd probably curse them, turn them into frogs, or mind-control them to kill each other or something like that (if she's still non-evil, she might just cast something like Fear and Expeditions Retreat, never to be seen again). In a world with real witches, witch hunts would probably would not be some random lynch mobs, but a mercenary group specialized for the task that you can hire. Going after witches would be just too risky.

Anyway, what was the original topic again?
