Nah it is still is how it works. Go outside into the wilderness and you'll get killed by something that wants to eat you. That is if you actually have dangerous wildlife nearby.

I mean they fight and kill each other, rape, eat babies of other specimen etc. Should we also be doing that for some reason?

Humans still do all of these things to some extent. We define what is moral and what isn't. Humans eating meat is one of those things decided a long time ago and it isn't going to change for a long time. There is absolutely no reason why humans can't eat meat. If you're worried about animal suffering then you better put together better laws. I'm not going to stop eating meat just because you're trying to redefine what is moral or not. I don't give a fuck about your opinion and I like the taste of meat. I do give a fuck if you try and make me stop eating meat that's when we have a problem between us two.
