I'm confused, there have never been a large group of people who would rape and murder. I'm not convinced it's even an order of magnitude lower now than it was 1k years ago (or 10k). The largest majority have also been omnivores (I'd include insects, eggs, and fish) for almost the entirety of that time. It doesn't look like we're going to either solve omnivorism or perfect non-violent world peace any time soon. On the other hand, I suppose a Matrix-like utopian hellscape could bring us both.
