It is disturbing to realize that all humans alive today are the direct descendants of the most successful committers of murder, enslavement, rape and genocide, and all historical injustice is just the documented tail end of success and failure in primate evolutionary competition.
It is not quite so dire. Within a cooperative group, rape and war are no longer viable strategies, and once everything is conquered or we have mutually assured destruction, only cooperative groups are left. But I do respect antinatalism as a position to eliminate suffering.
