From what I recall from both Archaeology class and Forensic Anthropology class, the majority of human remains found from hunter-gatherer societies either died from extreme cases of bad teeth,apparently non-accidental blunt force trauma to the head, or some other typically accidental bone injury to a lower extremity. I recall the FA professor specifically talking about how a great number of the human craniums found have evidence of human-caused trauma. As a side note, we had a pretty cool one in the class that shows evidence of the person actually living through it, as the bone began to regrow.
But yeah, I'm pretty sure hunter-gatherer societies were not full of the "noble savages" oft talked about in late-19th, early-20th century anthropology. I think they were likely savages, but not any more so than we still are today, as a society.
