Its 50/50 animals are killed by humans for our benefits but they dont have to do it. We could simply eat vegetables or anything from plants (which i think anything that comes from plats is a vegetable). So I think that the answer depends on who is answering the question if they are vegans or meat eaters (which i am myself).
