It’s possible that the nice-ifying effects of large populations on human behavior could cancel out the bad effects. But it’s not obvious that they do—and it’s certainly not obvious that the former exceed the latter. The default presumption would be that people who live in ancestral-type environments face a variety of threats, both human and natural; and that as people move into larger population centers, the threats they face become less natural and more human.
