I see many Russians already enraged about the war, some even doing protests against it. The fact is that most feel powerless and afraid against an autocratic government, and I feel it’s very hard to tell them to retaliate when their lives are on stake. (Maybe your country hasn’t experienced this yet, but hearing anecdotes from my country’s past I understand it’s really hard to mobilize when the next day you can be kidnapped by the secret police and end up in a prison cell where you get tortured to death.) Resistance is necessary, but it’s far easier said than done.
I just don’t see a point treating ordinary Russians as “sinful” because of this event. If you’re enforcing standards like these on everyone, then I guess the entire US population is also responsible for all the the war crimes and atrocities the country has done for decades. And I don’t want to do that; even if the current elite controlling the US has done some of the most atrocious things in history, I don’t think the people living there “deserve” worse lives because they haven’t retaliated.
