Between 2014 and 2022 they killed lot more civilians than Kazakhstan did, through indiscriminate bombardment of urban areas, you know, activity that everyone is fine with as long as it is their side doing it.
And Ukraine is more inept than Belarus, exemplified by the fact, that despite being the most developed part of the USSR, they had lower GDP per capita than Belarus ever since both countries became independent.
And at the same time Russia launched arty on Ukraine from inside it's own borders to support the Donbas, and Ukraine was forced to refrain from hitting them because they were on Russian soil.
Ukraine had legit reasons to be striking targets inside Russia itself for years now, and held back till Russia moved troops in to invade.
Ukrainian's used arty against the Donbas rebels because said units had their own armor and military equipment, plus the 'little green men' of Putin's bringing their own stuff, is not some sort of war crime. Also, from what I remember seeing, most of the 'indiscriminate' attacks in the Donbas were later found to be Russian arty hitting Kyiv supporting civies, or their own rebels, and blaming it on Kyiv.
The Minsk agreement was supposed to end the fighting, but in reality all it did was tie Kyiv's hand's while Russia did whatever it wanted on it's own soil, where they had guns and such with the range to strike into Ukraine on the rebel's behalf, while the rebel's themselves barely even attempted to adhere to the Minsk Accords and were always aiming to go independent or 'join' Russia.
Also, Ukraine's economic woes were set to be solved by the oil deposits found in 2012, and even had Exxon and Chevron contracts/equipment set to go. Then 2014 comes around, and suddenly Putin and Washington both find reasons to stir unrest in Ukraine, for different reasons. Putin wants the oil/strategic defensive positions at the edges of the Carpatians, and that's part of why he annexed Crimea (to claim it's EEZ, not just the naval base), while Washington didn't like that Yanocovych(?) decided at the last minute to back out of the EU deal and try to remain 'neutral'.
As I've said before, this mess is one where no one's hands are clean, including Ukraine's gov. The only reason the conflict came onto western public news feeds is because of MH17's shootdown and the shitshow around it; the Maidan didn't make as much news with western normies as the shoot down did. I remember seeing the hastily deleted rebel posts bragging about downing a transport, as I happened to be surfing Twitter and SB both that day.
Trump told Putin he'd nuke Moscow's 'onion domes' if Putin made a move on Kyiv, and Putin seemed to have actually believed he would (likely because of Trump's actions with regard to N. Korea), while Biden/Pelosi (who's really calling the shots) impeached Trump because he dared to want Zelenski to actually look at the shit with Burisma and Biden's son (Pelosi's kid is also peripherally involved here, which is the real reason Pelosi pushed the Impeachment). Neither Biden or Pelosi were willing to nuke Moscow if Putin moved on Kyiv, but both were willing to open the coffers and crank up the mil-ind complex to supply Ukraine and our other allies, while getting a rallying event to attempt to boost Biden's shit polls.
I have no idea what the best outcome for this conflict is, but I'm not going to pretend that any side is 'clean' or that the West's motives are 'pure' here, even if Russia's are worse and the least justified of the bunch. Ukraine at least has a far more justified position because of how Russia has breached their sovereignty and Putin dismisses their existence as a nation-state.
Edit: Also, this happened.
