Not mutually exclusive. "We're incredibly powerful and government is evil" and "we're absolutely going to use governmental power now we have it to fuck shit up that we don't like", is totally a position those in government can take.

The key is in the idea of governance and who's governing. Any and all governance which has happened by those the people in power don't like (basically the other team) is what is labelled bad.

The only question is, ultimately, is their governance sane and sensible? From the perspective of the greatest good for the greatest number of people.

And no. No it isn't.
