While out drinking with some friends we got to talking about villains in popular culture and it ultimately devolved into this discussion again; the question is as follows:
You have the chance to ensure the continuation of the human species for next 10000 years, but in order to do so you would be labeled as the worst monster in human history for all time. Would you do it?
In this case you would have to do something that would cause you to be labeled as the most vile human to ever have lived. And assume there are no outside threats for those 10k years.
