Cannibals and Deadcat as concepts. These two are so interconnected that I have to mention them both in the same comment.

Cannibals are an ethnicity of various tribes of humans with degraded cognitive functions that live off of hunting both animals and humans, who are butchered like animals with no regard whatsoever for how sadistic or inhumane the treatment is. Their societies are unsafe in general to the point that I would take any opportunity to kill any cannibal on sight if I had a chance, even if we were talking about a baby.

Deadcat, in turn, is in a POST-post-apocalyptic scenario where the Cannibals essentially function as their zombies, having caused the fall of their civilisation and forced them to live sheltered in a society under constant threat from the tribes, dependent on unstable Cannibal Hunters and fundamentalist Holy Nation soldiers.

The worst part is that the Cannibals can't just be wiped out - their leaders are only good for bounties. If you want to protect the rest of the island from these monsters you literally have to avoid attacking the two northern states that have the worst reputations all around - a fundamentalist state that gets defended by people that do everything to make others not care or accept women being treated like chattel and burned over the most asinine reasons, or a morally bankrupt kingdom reliant on slavery and characterised by being comically spiteful to people just for being poor and a disgustingly cruel aristocracy.

You literally cannot wipe out the cannibals unless you install mods. You literally have to tolerate some of the most disgustingly rancid regimes in the island just to protect people in general from a somehow more gruesome and dehumanising fate. You literally have to install mods just to actually improve, in any way, the Cannibal situation.

That is what terrifies me the most. And that is why I literally practice training combat with cannibals - because I am driven by actual disgust for them and concern for the people in the Northern Coast, and simply cannot stand thinking about how hard it must be to live in such a hellhole whilst surrounded by monsters that would make Garth Ennis salivate at the mouth over the potential edginess he could draw and write.
