Will people ever stop abusing power?

No way in hell. The upper class fights to keep their power by oppressing the lower classes. The middle class tries to overthrow the top and take over under the ruse that they're trying to help, but become just like the last upper class in the end. The lower class is to pushed down to have ambition. It's a cycle.

Nope man is too greedy

Yes!😋 (Actually, I don't think so)

No, because power is the only way man can express their superiority to others, and that's what mankind is like. Always seeking for power and always wanting to be above others.
