The issue is outside of any “true” morality, if you were in Russia chances are you’d be doing the exact same for the other side, since moral justifications for violence can be constructed and consented to on behalf of the public through many methods. Retribution violence is propagandized heavily in the US, in media and civic life. Some people gleefully imagine themselves inflicting violence with their firearm of choice if only provided with the right circumstance. So all this becomes a matter of dividing people by who is morally granted to inflict the violence they’ve been conditioned to view as justified, perpetuating the cycle. Viewing history as a river of blood and ignoring the banks of the river where people live their lives.
