Terrible Ted (and I mean awful)

As humans were settling in agricultural societies, they gradually started to behave very differently compared to hunter-gatherers. They began to privately own land (which, by the way, was inconceivable to hunter-gatherers, who saw the land as a sacred gift of nature to be shared by all), as well as animals and other resources.

This, led to social and economic disparities between humans. Resources weren’t enough for everyone anymore, as they used to be until that point in time. Naturally, humans felt more and more compelled to act selfishly in order to survive and gain competitive advantage.
