Evil
My post on Kekes (please see, just below) mentions the prevalence of evil, and some might doubt that there is that much evil. Well, one yardstick for telling whether human nature is largely evil - not to say "mostly," but just "largely," to leave it ambiguous - is the fact that the UN is largely evil. You could say that humanity is 98% good, with just a handful of evil oppressors holding power and holding sway at the UN. But cultures, people, produce evil oppressors. A society which century after century produces only evil dictators is likely to have a largely evil culture. And culture is produced by human beings. Moreover, the UN is hailed as legitimate, though it is largely evil. So, Kekes is right.
