It is easy; nations that attack other nations unprovoked are "evil" (at fault). Ukraine has never infringed on Russia's sovereignty or territorial integrity before it was attacked. Therefor this war is entirely Russia's fault. The world is mostly shades of gray. But this case it black and white.

It's not even that there was absolutely no active process of joining NATO when Russia attacked Ukraine in February 2014 and started all this. No; if Ukraine wants to join NATO, that's entirely Ukraine's decision. Russia has no say in it. Ukraine is sovereign and can join any military alliance it wants. Just as Russia is free to do so.
No nation has extra-territorial security interests that it needs to defend by attacking a neutral, peaceful and friendly neighbor.
You have been fooled into defending imperialism. Or worse; you're consciously defending imperialism.
