I'm sure everyone would agrees that the ideal outcome is everyone getting along and singing Kumbaya, but Russian oligarchs losing their wealth and influence to "the deserving rich" is still a win for meritocracy in a very narrow sense. It's sad that people had to die to arrive at that outcome, but at the same time it's not like we made a decision "hey should we start a war to knock the oligarchs down a peg?". Moreover it's questionable whether the oligarchs even "started" the war in any meaningful sense. I'm sure if you anonymously polled them, they'd all prefer if the war didn't happen. They didn't do much to stop putin, but in a country with weak human rights and rule of law, the most likely outcome of them opposing putin would be them mysteriously falling out of an apartment balcony one day. Saying they "started" the war is like claiming the average democratic voter in the US "caused" the ICE killings because they didn't fervently oppose the trump administration enough.
