Aren't there even to this day completely pacifist tribes in South America and I wanna say island tribes somewhere out in or around New Zealand or New Guinea?
No idea but wasn't exactly thinking of tribes as society. More the overall whole of humanity. I wonder if we'll ever achieve a world without hate (excluding exstinction).
Sorry I knew what you were going for, I just took issue with the word society, because not calling those tribes a society is a kind of colonizer mentality. It's actually really sad, one small tribe is in the rainforest and they keep getting killed and rolled over, sometimes literally, by Brazilian mining companies.
