Depends whether you think killing people for having an opposing view to you can be justified in any circumstance I guess.
Last time I looked, the US wasn't killing people for opposing the government.
Russia on the other hand just lock them up and slowly poison them like they're doing with Navalny, so I guess it's like a drawn out death sentence really.
Do you value free speech and the fundamental Human Right to it? If so, why tolerate it anywhere, rather than shrug shoulders and say "not our problem, doesn't affect us".
Can't see there's anything particularly "white saviour" about protecting human life
