Moral Event Horizon: Gorrister and the Imperial cannibal crew commit this with their eating habits.
Squick: The novel is loaded with it, mostly through the descriptions of peoples' deaths and certain plot points in the latter half, most notably of which are the cannibalistic Imperial survivors that try to eat Sartoris and the appropriately-dubbed 'skin hill' that Trig finds made of limbs, corpses and zombified remains - including his brother who has half his head missing.
