I think there are other ways to fight authoritarianism. It can definitely include violence, but imo only as a defensive measure. Right now it's all about the offense.

I also don't think Putin or its successor will all of a sudden become non-authoritarian when Ukraine wins back all territory. The threat (and fact) of Russian leadership oppressing people will stay, regardless of how far the Ukrainians push back the Russians. Setting up defenses will be needed regardless of how this war will end.

Right now innocents are dying in terrible conditions over this political play. I understand that you believe that that is less important than winning back territory, to the point that you support creating more suffering and death by letting other parties bring more death machines to the war. I think I have clearly outlined that I value these things differently.
