I think neither "righteous" nor "evil" are appropriate words in this context. It's a real-world institution with the expected biases, missteps of authority, episodes of getting embroiled in political machination, etc. Demonizing it is just as naive as idealizing it. And there's probably much more of the former than the latter today, when a lot of unearned, easy cynicism is either unconsciously performative, or even worse, the outcome of a caricatural conspirative worldview.
