While I agree with the sentiment that at the end of the day none of this would've happened without the Russian aggression, it does still matter because intentionally targeting civilians is a war crime. I'm not saying that's what happened here but let's be clear that actions have serious meaning in war. This line of reasoning reminds me of the idea that we shouldn't care about the origin of covid because it's out there and the origin isn't going to make much difference at this point. But I think a lot of people do care about these details because they might have great historical significance.
