Cue the melodramatic speech about how sometimes, like in [pop-cultural cornerstone conflict], the morality is clear and simple, and if you don't support [the particular side of the speaker], you're clearly in the wrong...

Yeah, given how the specifics in square brackets above tend to differ depending on the speaker, I think the world would be a much more peaceful place if people like that were manipulated into going after each other, and leaving everyone else alone. Which, funnily enough, is most likely what's going on in Ukraine right now. I mean, Azov wannabe Nazis versus Chechen fanatical cut-throats and Syrian mujahedin - let'em duke it out and pass the popcorn while you're at it.

Pretty much. It's kinda like how southern republicans routinely disparage democrats for being the "real" supporters of slavery in the Civil War... then double back saying the war was totally not about slavery, the (democrat-led) South was totally in the right to fight, etc. It's one thing to say that reality was more complex than a simplistic black and white vision, but it's outright inane to just try and flip the narrative for its own sake.

In this case, Ukrainian forces do have battalions openly endorsing Nazi or Nazi-like imagery - likely for the same simplistic mentality of "Russia bad => Nazis good", without any deeper understanding of the ideology. In turn, Putin is using that for his own propaganda purposes, since it's a narrative much easier to follow than the actual situation with ethnic Russians in Donbas for the past eight years.

As to who is "good" and who is "bad" at this stage - personally, I wouldn't mind seeing the Ukrainian version of the Patriot Front get steamrolled, especially if the canon fodder selected for that purpose is mostly comprised of their equivalent Chechen and Syrian lunatics. Ideally, they'd slaughter each other, and the world will be ever so slightly less violent in the end, which is always a good thing.
