Lord Foul
I don't spank men
Ooo alien machines, i like your line of thought.
This line of thought ends with the Reapers returning to cleanse the galaxy of organic life.
I think a caveman would be n equally as effective metaphor. They lived just like the wild animals of today. Fight or flight, only the strong survive. All instinct, no emotion.
Which, if you think about it, is really fucking scary. I wouldn't have made it long in a primal age. It'd be like the absolute worst of modern humans succeeding. Big, strong, mean individuals with no remorse for killing ruling the lands.
But really it was the individuals with enough ability to work together to form small communities that won out over the powerful lone alpha males. With the advent of society over anarchy as the most successful survival model, I think we can see our justice system evolve from "punish the transgressor" to "protect the interests of the community."
