They come from a time before people realized that revenge was an endless cycle. Like the old testament was full of that, where good and evil were mostly framed in terms of “good people are us, evil people are our enemies, and it is good to cause suffering to the evil people. Also, sometimes circumstances make one of us evil, until we stone them or something”.






Lol yeah, I should have included that the emotional immaturity was such that they believed wanting revenge on a group for things they had nothing to do with or for reasons of jealousy/envy was normal. It was an attempt to continue your joke that the story creators were didn’t even have the logic to consider that angle.
Or they were smart enough to make up horrifying stories that would stick with people and prevent them from doing dumb shit like going to play in a swamp and just saying “don’t play in swamps” will make some people even more likely to play in swamps to prove they can.
