Would you describe your inner circle of friends as "quite awful"? I really hope you wouldn't. I certainly don't. And I presume most people don't. So there must be sizable amount of human being that another sizable amount of human beings consider good humans. The CEO of the multi-billion dollar company I work for seems and acts like a normal (meaning decent, as opposed to your definition "quite awful") human being. Never goes on rants like Elon, quite worker-friendly, always there to chat, doesn't fire people on the spot because they can't answer a question that he only started verbalizing halfway though his stream of consciousness rants. And we compete in the same industry as Elon. Isn't trying to influence politics with his position on several dozens of matters that have nothing to do with out company. Also doesn't cultivate a cult following with himself as the head of the cult.
That's all that matters to me, if there no evidence of him being an awful human being, it would be downright unethical for me to assume that he is an awful human being hiding behind a facade.
Also: Before anyone hits me with the "Well your CEO isnt a visionary trying to get us to Mars". Well, yeah. I'd rather be stuck on Earth with him than live under whatever fantasy a sociopath is promising to unfold on Mars.
