Violence is immoral and wrong. Justifying it is a stretch but doable. Your bias determines the general feelings you have towards a certain war.
Western violence perpetrated by the US and allies against multiple nations have never been up against the same level of scrutiny, false information and downright attempts to misinform and disinform the global community as this Russian one.
As a person, I cannot condone what Russia's doing but I can also concede this is their choice and their business. Am I going to be condemning them? I could only really do that with any honesty and decency if I understand the entire geopolitical picture and their justifications/motivations. They cannot disclose everything they know either. At this point, American wars have been just as if not more bloody, violent and even less reasonable even just at the surface of it. Until the day the US has to pay in full for all its crimes against other nations and humanity, how can honest and decent people begin condemning Russia? This isn't the bullshit "oh that's whataboutism" from the usual Reddit freedom army neo lib and conservative morons. This is pointing out the criminal and dangerous double standard. If allowed to perpetuate, grants the US led Western world undue power and right in determining for everyone what they can and can't do and what they can and can't say and think. The West has proven itself to be thoroughly evil and a cunning propagandist. So why would neutral peoples want to support this? Because the West is glossy and rich due to the riches they stole and plundered for centuries? Riiiiiiiiight.
The West desires to rule the world and enslave all in a hierarchy they consider "rules based" and "ordered". Those who benefit from it are naturally in full support of it.
The genuine reasons for all this is never said and if muttered, must be shut down immediately via censorship, hordes of trollish comments, ad hom attacks, and character assassinations like calling someone a "tankie" or "50 cent army" "bot" etc etc... when the reality is so far from that. People don't want to admit the reality. Everything has been and is about power, money, wealth, resources, and its distribution.
Why do mainstream narratives continue carrying on with the lies and the repetition of that facade? Because it's able to poison the well so to speak. Propaganda and brainwashing works by making empty claims and unfalsifiable statements. Repeat that often enough and everyone no matter who it is will begin believing it.
The only counter to being brainwashed is to ignore all information and question it all. Listen and read, combine, assess, test, re-evaluate likelihood, LISTEN TO ALL SIDES and get BALANCE. Re-evaluate constantly. Do not allow yourself to be convinced of ANYTHING.
But human intellect and emotions do not make this easy or even possible in many cases.
