On the other hand, its easy to come to the conclusion that people in Russia will suffer a lot. That is sad because they dont deserve it. Also the fact that they are trapped in Russia is terrible. Very few ways of getting out of there due to all the countries closing their airspace.
IMO it would have been better to open the borders for both Ukrainian and Russian refugees (prioritising Ukrainians of course) and stop making business in the future with Russia, but without stopping the current functioning of the economy. This allows people to think about their future and move out of Russia without a lot of friction. In the long term, more damages for Putin's government.
