I don't see NATO wading into Ukraine wanting to torture and kill people.

NATO waded into Afghanistan and Iraq and killed two million civilians. NATO is funding and participating in an ongoing genocide. They've killed many, many more. Guantanamo Bay is an illegal torture facility, there are undoubtedly hundreds more we haven't heard of. The downfall of its hegemony would see the lives of millions of people saved globally.

Russian peace means russian torture chambers and mobile crematoriums for Ukranian opposition. Followed by generations of autocracy.

What makes you say that? You must understand that's a cartoonishly unreal accusation, right? Yeah, Russian democracy sucks, but not meaningfully moreso than Ukrainian or most Western democracies.

Fighting for the re-conquering and oppression of the eastern half of Ukraine (i.e. DPR and LPR), oppressing Russophones and continuing to explicitly deny the regions a right to self-determination. Zelenskyy already admitted they would not vote to stay part of Ukraine given the chance. That will not be a happy outcome for a lot of people either.
