"justifies violence" 😂
No sane person thinks violence is never justified. Russia is trying to invade a sovereign nation to steal their land and resources, and they're raping and murdering the population in the process. It's just common thuggery at a large scale.
If you don't think that justifies violence to stop the thugs, you've got something seriously wrong with you. Particularly in this case: Ukraine blew up ammo depot's full of weapons that were going to be used by those thugs to kill Ukrainians.
