In psychology, there's a mechanism that tells us to look for extraordinary causes for extraordinary events. And I don't mean here something seemingly supernatural - just something that affects you in a big way. For this reason some people, when they lose their loved ones, can't simply agree it was an accident and look for some kind of conspiracy, a bad actor, a murder.

My point is, even those russians who know the situation well on the level of knowledge, could be emotionally detached and think that's just how the world works - but now that they see unprecedented response, it can sink in emotionally that their government has really done something terrible.
