People have always killed other people. Some people even eat other people. And we let them. Have you tried to convince a lion to eat a soy gazelle? I suppose not, because of the strong language barrier. They would probably not digest it very well, as they are real carnivores. My point is, we are capable of having this complex discussion with several points of view and your whole reasoning is "animals eat animals, why shouldnt I?".
