I just don't think human psychology works this way. Your attitude is akin to a parent's with a child, "your actions have consequences, so do better". But Russia's parent in this analogy is Putin, and he will use such things to his advantage. Your approach might feel just, but the message will be completely lost.

You will note how many Western governments over the past few days have been saying explicitly: "These sanctions are not meant at the Russian people, we see that they did not want this war". It doesn't seem like this is even true from polling, but it's calculated messaging, and it's important.
