That is not the nature of humans. That's the nature of some humans to rule and enslave others. Some people just want to be left alone - I would argue that most people want that. Then a group of thugs comes over, sets us fighting against each other, calls it a democracy and feeds off our labour. I wasn't asked to sign any kind of contract with any government, I was never asked if I want to pay taxes to finance things I actually despise. If you believe our society ought to be humane - help the poor, provide for elderly etc. - then convince me to give you money voluntarily and convince me you can do a good job of helping the poor (and keep convincing me all the while I'm paying you). Governments pretend you have a vote that makes a difference, then they just rob you indefinitely.
