GENGHIS KHAN VS CRUSOE

What provides genghis kahn with the incentive to (a) let you live, (b) keep your things (c) let you remain free of slavery (d) Let you keep a portion of your production?

It’s the inverse of the Crusoe’s Island thought experiment.

Historically, the model that we evolved with, is an evenly distributed but scarce population preying on one another to obtain territory, women, and goods.

How do you develop mutually beneficial cooperation in the historical (existential) rather than pessimistic (Kahn) or optimistic (Crusoe) models?
