You assume every society must produce madmen, misanthropes, ect..., I'd suggest those are only produced by societies failures.
I make no such assumption.
I have yet to see a human population that doesn’t have to deal with these issues. Why? Because those issues don’t necessarily arise from problems with society- some arise because humans are imperfect beings. IOW, society hasn’t failed- genetics, illness, injury or other factors have contributed to a failure within the person.
