I think it is partially true. The vast majority of human beings don’t act like that. But it seems the ones in power or close proximity to power do.
This is why it is important to have societies where various forms of power are managed carefully. Limited constitutional government with guaranteed freedoms and checks and balances for example. Regulations placed on mega corporations is another example. Restrictions to prevent the powerful in government or business (or both!) from messing around with the rest of us…
I don't think there's much secret evil out there. I've taken a look at some people that were officially in power for something - they were nice handsome people - sometimes a bit stupid. I think the biggest problem is stupidity. Stupid people in power will do powerful stupid things - while they think that they're doing something great. The more intelligent ones can change their minds quickly if you feed them with good arguments - but that's not easy, because they often live in a bubble and are out of reach.
