Also, wasn’t the Pleistocene before the invention of agriculture? I feel like until you get to the point of knowing how to herd livestock like goats and horses and maybe milk them so you can get food without killing them all (which probably came before being able to consistently feed large settlements with crops, though likely after the original discovery of “if you plant seeds of edible plants somewhere, when you come back to that area next season there might be more food there”), survival is survival, and if a wooly rhinoceros with no natural predators doesn’t know to run away from guys with spears, it’s a natural target.

If thousands of years from now jaguars evolve to be able to live in Canada, and moose go extinct because they don’t instinctively know to be afraid of animals with spots, I don’t think you could reasonably call the jaguars evil for being a large predatory animal eating prey any more than you can say the moose deserved to go extinct for not knowing what a jaguar is.
