I don't quite think so. They know what they are doing is wrong, but they justify it with "My enemies do worse things, so comparatively I'm still the good guy." That's why qanon is so successful, and conspiracy theories in general with people like this. An invisible, imaginary enemy will always be morally worse than them, no matter how disgusting their behaviour gets.

I think it's more that reactionaries have an outsized belief in how good they personally are. Because they are so certain they're a good person, what they're doing can't be bad even when they'd demonize someone else for it. This belief is reinforced in all the classic stick-up-your-ass conservative institutions: they go to church so they're godly, they back the blue so they aren't some criminal, they put their head down and grind at work so they deserve whatever they can get their hands on. It's individualized exceptionalism.
