I feel like this doctored version of history benefits the Carnivores - saying they were nice from the start, the Herbivores were unreasonable and started a war, the Carnivores wanted to stop, and then A WHALE SHOWED UP and they stopped fighting. And now, in a society where the Herbivores are protected and the Carnivores have to hide their true nature, shouldn't the Carnivores reclaim their power? That's the lesson I think they're trying to teach Jack.
...except, at the same time, they're saying that the "old ways" were pretty much the same as the current times? living in harmony, NOT eating each other? So if their aim is to incite a Carnivore rebellion, that doesn't seem like strong bait.
And if they want to preserve the Herbivore supremacy, then the story doesn't do a good job of that narrative, either. I guess it implies that Carnivores have always been savages, and need the Herbivores to keep them in control? But I don't get that message very strongly from the story, either.
idk, I'm assuming this history is fake (or at least heavily twisted) because of all the plot beats letting me know it's a Bad Thing and driving Jack fucking insane listening to it. But I can't figure out who's side it's slanted towards. Maybe there's a 3rd party who benefits the most from this? But the only third party would be the Sea Animals, and their whole deal is "not giving a shit"? Or maybe the story isn't done yet, and the truly horrifying details will make things clear.
or... I might just be an idiot and this is all going over my head.
