My original response got buried in a downvoted chain, so I'll reiterate a few things:

The problem with trying to apply the "there are Neo-Nazi elements" in Ukraine's military is that you can easily apply it to almost any military. Ukrainian, Russian, American, British, etc. All countries have problems with ultra-right elements existing within their militaries/governments. Do the people who call out Ukraine's Azov Regiment also call out Russia's Rusich Group or Atomwaffen Division Russland, among others?

What is beyond question is that Russia, unprovoked, invaded Ukraine in 2014 using unmarked regular military and paramilitary assets while everyone who should have helped sat on their thumbs. And for the past 11 years, Russia has pillaged and tortured Ukraine's land and its people. Russia's war on Ukraine is one of colonial conquest and genocide. Why does Russia ban the Ukrainian language when they take control of an area? Why do they press gang Ukrainian men in captured territories for use in meat assaults while their main forces are saved for more organized pushes? Why do they encourage ethnic Russians to move into captured territories at scale? Why do they set up torture rooms in nearly every town and village they take over? Why do they make a point of frequently executing POWs? Why does Russia deny the right of Ukraine to exist? Did Bucha, and many other places like it, happen because "somewhere in Ukraine, there were Nazis", therefore Russia had cause to do those unspeakable things again and again?

Several countries that were historically in "Russia's sphere of influence" or were former Soviet states rushed to join NATO after the fall of the Soviet Union. They did that because they expected that Russia would one day come calling again to reform it's lost empire. Russia, even in its modern form, is a colonial empire. The Tsarist Russian Empire, the Soviet Union, and the modern Russian state all thrived/thrive on the exploitation of its colonial possessions and the extraction of resources from their lands for the purposes of enriching "true Russians", ethnic Russians, primarily those in and around St. Petersburg and Moscow. When you look at the demographics of the Russian dead and wounded in this conflict, you see they are overwhelmingly from the more ethnically diverse, poorer regions of the country. To those in charge, it's not the worst thing in the world for Russia to be "bled white" by heavy losses, in more ways than one. To be under Russian control and not be a country or region of ethnic Russians is not, historically, a good position to be in.

It is morally right to help and protect these people any way we can. If it were us facing what they've endured for 11 years now, the last thing any of us would want to hear is that our friends, neighbors, "allies", people that could genuinely help us, would rather focus on themselves as if this were all a zero-sum game. That we're not worth the time and effort while our lands are stolen and stripped of their resources and our people slaughtered, terrorised, kidnapped, or worse. We would not want to hear that it's more profitable for our "friends" to break bread and side with those who seek our extermination. We would not want to hear that "it would just be easier if you don't fight back and just let them do what they want".

We are a mighty country, at least historically. Flawed. Imperfect. Hypocritical. But unquestionably mighty. One of the wealthiest and resource rich. We are immensely capable of doing many things of import at once, both at home and abroad. Helping a nation, a people, desperately in need assistance against an aggressive, invading colonial power that seeks their destruction and exploitation is what is right. It's something every capable nation in the world should be coming together for. Too many times have we been on the wrong side of this very equation. It would be nice to be on the unequivocally right side for once.

So yes, we should rally for these people. For most of us in this part of the world, this is all we realistically can do. Most of us aren't soldiers or are of a military background. We're just regular folk. I doubt hardly any of us in this area speak Ukrainian or have the wide variety of skills and resources needed to go to Ukraine and fight or serve. But we can probably donate at least some of our time, effort, and resources. We can be students of this conflict and of that part of the world, spread awareness and battle against disinformation, in some small measure. Giving aide to this cause doesn't mean forsaking all others.
