My understanding is that it's a settled question and that the evidence of extremely high homicide rates in hunter gatherer societies is overwhelming. If you have any links suggesting otherwise, I'd be interested in seeing them. As for relatedness, that's relative (no pun intended). If everyone within 200 square kilometres is at a genetic distance of a second or third cousin, then a second cousin is the base for a non-relative. In any case, regardless of why precisely it is that violent death is so common pre-modern and especially pre-state societies, it's abundantly clear that it is. Regarding low population densities, you'll notice that Australian Aborigine tribes are represented in that chart and exhibit murder rates that are far higher than those in modern societies. They do however have the lowest homicide rates among hunter gatherer tribes. The highest homicide rates are found in the Amazon rainforest, where population densities would be highest. So it appears that the two factors that contribute to high homicide rates are pre-state/agricultural society and high population density, and that in the case of the tribes living in the most sparsely populated regions, the inhibiting effect of extremely low population densities on homicide rates does not make up for aggravating effect of living in pre-state societies.

It is clear that homicide rates were higher in the past than they are in modern societies. What is not clear is whether hunter-gatherer homicide rates were higher than those of pre-modern agriculturalists. Here we are primarily comparing band-stage forager societies to other forms of social organisation/dietary lifeway (tribal gardening societies as found in much of Oceania, for example). Of course relatedness is relative, but the argument is that encounter rates of whatever a group deemed "non-relative" were relatively low and that hostile contact was very costly/relatively unproductive. The "other" was known, cementing feelings of kinship, but distant. The most violent societies according to your charts are post-band but pre-state with relatively high population density. That is not in contradiction with the "foragers nonviolent compared to other pre-state and comparable to earlier state societies" model. The interesting question is whether there may have been two optima for human organisation - one at very low population density mobile foraging, the other at the point of the modern state. The modern state may be preferable to the first optimum, but the idea that it takes 10,000 of evolutionary search time to find the second hill is fascinating.
