The majority certainly doesn’t choose the active misery of others, and on the scale of the Lord of the Flies setting, humans have consistently shown collaboration and mutual aid. We’ve documented many instances of stranded groups, and even some people that volunteered to be stuck on a raft together for months, and they always choose to work together, despite their differences. Capitalism, fascism, and radical individualism/nationalism are the root of the societal scale evils, because they’re ideologies that propagate in the hands of the few that are willing to benefit at the cost of the many. Humans have not always lived under capitalism.
