NATO did not fire a single shot during this war. Russia was the one who started all the shooting. Not to mention that Ukraine is a sovereign nation that gets to choose if it wishes to associate with NATO. Russia decided to use force to prevent Ukraine from doing that.
There is no history or geopolitical context here that justifies Putins invasion of Ukraine. To claim anything else is an endorsement of Putins flavour of fascism, where he is literally saying that Russian might makes right. It’s insane how deluded you are to literally draw the opposite conclusion from facts that do not support your arguments at all.
