It's already known since WWII and the Battle Of Britain that bombing civilian populations doesn't decrease their resolve, quite the contrary.

Whilst some of Russia bombing (such as that of power generation) does make military sense, for the last year or so it looks like strategically Ukraine is way more effective at damaging Russian war efforts with long range attacks than the other way around.

Further, it also looks like Ukraine, with it's proportionally much smaller territory, is much more effective at AA defense.

It's funny that since Ukraine started making their own weaponry for in-depth attacks (as, shamelessly, Western powers did not provide them from the start with cruise missiles), Russia's "Big Country" advantage is being turned into a disadvantage.
