Based on what evidence though? It's fair to have a subjective opinion of someone but when I think about these words 'egotistical' and 'evil' it's not clear to me why Elon is any different to a regular person.

For example, if we start breaking down the meanings of those words....

egotistical :- excessively conceited or absorbed in oneself; self-centered. evil :- profoundly immoral and wicked. immoral :- not conforming to accepted standards of morality. morality :- principles concerning the distinction between right and wrong or good and bad behavior.

It's pretty clear some from of the some interviews that he's done some things that could be considered egotistical like working his employees to the bone. On the other hand, he does pay them well and it's nearly impossible to run several multibillion dollar companies without solving real world problems and helping people which is quite the opposite of self-centered.

Evil is a much harder term to grasp. Elon is certainly no saint, but I'd struggle to find something he's done that would be considered truly evil. He's been married multiple times and known to have cheated. Immoral yes, evil? Probably not.

All I'm saying is, I think there's plenty of worse people than Elon.
