You could expand that to just power in general. There have been amazing and horrible leaders in both the dictator category and democratically elected leader category. Democracy’s main advantage over dictatorships is that it has mechanisms to deal with the bad ones, though even those can fail with sufficient bad faith in the system.

That’s why I think the fediverse needs a robust mod monitoring and evaluation system on instances with good faith admins (instances with bad faith admins should just be avoided entirely). A guide for how to mod/admin in good faith and a way for users to evaluate that would also be good.
