To answer the Ukraine question first, I think they continue to do the same, which is act professionally and logically to fight and win a war. If you saw the video of the Russian whose leg was trapped between a building and his BMP that crashed, he asked the Ukrainian to finish him. Which the Ukrainian responded to by slapping the Russians forehead and saying "We are not like you!" So I don't worry about this type of actions changing the Ukrainian response...which has generally been great.
For how the Russians little will change, and I expect more of this....but the issue is they have to use missiles which they have already used up in large numbers and which they can't manufacture any more (due to sanctions). So they will continue to expend stocks of high value, and almost irreplaceable, missiles on infrastructure and civilian targets thinking this will weaken Ukrainian resolve and make themselves feel good about "doing something". But it will have almost no military value and will only make the Ukrainians and free world see more of Russia as the horrible entity they are and also how impotent they are as a military because they are not good enough to use these resources to strike military targets to ... you know... try and win the war.
In Syria they had air superiority and could drop cheap and easy to get dumb bombs on any civilian targets they wanted. So in effect they could destroy towns, cities, infrastructure all over the country at-will, and they did so to break the opposition. The difference is that in Syria they could and did kill/destroy everything, so the option was defeat/death or defeat/life (albeit a shitty one under Russian/Assad oppression).
