Why are we feeling that a Russian victory in Ukraine is preferable? I had heard a Belarusian anarchist fighter reach the exact opposite conclusion:

If Russia wins here, there will be no independent trade unions, no human rights organizations, no grassroots structures for self-defense against the arbitrary rule of officials and the police. [...] There are no other options but armed resistance to the fascist regime that attacked Ukraine today. And you have to understand that today's war in Ukraine opens up a huge field of opportunity for anarchists which is important not to miss. For the first time in almost 100 years, we can now create a major political-military organization. [...] We are well aware that after the war, we will have clashes with the ultra-right, and with the state, which will attack the freedom and rights of the people. We understand very well that in the future the experience we will gain here, these structures, which we have to create here now, will be useful to us in our further struggle for a free Ukraine. [...] Another path awaits us - a dangerous path, full of compromise, full of pain in suffering and loss. But it is a path that can lead us to the emergence of a new, powerful, liberating movement, which can then change the whole picture in the region, later in Europe, and maybe in the whole world. [...] The last thing I want to say is to appeal to our Western comrades: we don't need your westsplaing, we need your solidarity.

Which seems like pretty persuasive reasoning to me.
