cannibalism is simply the act of eating flesh of your same kind. the connotation that it also implies a barbaric, tribal, and bloody nature is a separate entity.
A person forced to resort to cannibalism to survive can't be compared to another person that, aside from eating the flesh of their victims, also enjoys torturing them.
Ergo, the cannibalism trait is misleading, but only because the pop-culture interpretation of cannibalism also implies enjoyment. A pawn in rimworld that ate a human burger and got the negative thought is technically still a cannibal. a pawn that doesn't know he's eating a meal made with human flesh is also a cannibal. what kind of society/culture they came from will ultimately define how they react. Adding that kind of depth to rimworld is almost certainly not high on the priority list if it exists at all.
