>>2 (Zen) That'd just be The Purge though. Which winds up being rich can afford better protection systems etc and so have a higher chance of survival. Which is stupid.
I don't think anyone is really better or worse whether they're positive or negative, just different. Humans are fundamentally unique individuals and so trying to give an umbrella explanation for behavior is kinda moot. Like there are societal norms that some people strive to follow which I think makes up a bulk of human nature (wanting to fit in essentially), but then there is also the group that doesn't care about those things and breaks away from what is defined as normal.
So essentially there is no such thing as human nature since we are all different.
Unlike other animals we don't have a specific food source, a set sleep schedule, a mating season, a migration pattern, universal culture, etc.
