Modern Savages?

I like to think of myself as civilized, and well cultured. But what if I was isolated from society? How would I obtain nutrients? The answer is, I would do whatever was necessary in order to survive, which is generally true amongst most humans. If we think about it, if you had the chance to gather riches and fame, would you do it at all costs? Would you exploit and entire people, raping the land and murdering the men? If your hedonistic behavior bore no consequences, and only boosted your ability to succeed, I doubt anyone would hesitate to gather that power. We're all animals, we're all here to survive, and we do that by competing against each other. Essentially, the weaker beings have no chance against the educated kings of commerce. There is no calming the beast that lies within us because we are all born with the inherent barbaric tendency to survive against all odds.
