The problem is, as people gain power, it rots their mind and ruins their perceptions, so we have this recurring theme running throughout our history.

This isn't actually observable, though. Having managerial positions, administration, etc doesn't cause cognitive deficiency nor a "turning evil" in a religious, supernatural sense. What actually happens is classes act in their class interest. The proletariat as manager isn't seeking to establish itself as an entrenched, permanent ruling class, but instead to abolish itself as a class. Capitalists, monarchs, etc. all seek to maintain their individual privledges.

What is natural for human behavior is detetmined by the conditions of our social existence, ie how we produce and distribute. This means the idea of a static, fixed, unchanging "human nature" that cannot handle organizing at scale is false. The reason these myths persist is because they discourage action against unjustifiable systems today.
