Gorilla are pure herbivores, chimpanzees are predators which mostly eat plants, I don't know about Bonobos, all that's talked about them is their seed life, and homo varies from pure carnivore (in cold places, those with few edible plants) to scavenger to omnivore (especially in the tropics and places with fruit) depending on environment

Homo, of course, has been lying to itself about what food best sustains it, we can't live happily on the excess grain we've been producing for the last 10k years

By far the most dangerous predator on Earth is humans, we eat each other, anything that moves, kill for fun, build machines to do it for us, design what we eat to be easier to kill, and have you dealt with women? We're a scary bunch.
