Carnivores, why don't you eat other apes?

Including humans. Most apes are vegetarian, and some eat pretty much only fruit, except Chimps, who eat a lot of ape meat, including their own kind. Taking diet from nature, either humans are like the bulk of apes, and eat almost all vegetarian diets, or we're like Chimps, and should eat human as a natural part of our diet, right? Of course, Chimps don't have to cook their meat to get it through their system. I'd imagine our closest relative, the Orangutan would have to cook meat too, so it just doesn't eat any.
