Indeed. The Germans started strategic bombing of civilian areas about 88 years ago, and in fact, the German president was just in Guernica paying his respects to the victims of that attack: https://www.theguardian.com/wo....
We haven't stopped strategic bombing of civilian areas just because they don't work, it's also because it amounts to war crimes. Britain bombed Germany like that as a response to Germany doing it to Britain and that being the only response Britain could muster at the time, but RAF Bomber Command has always been down played because of the perception that it was wrong; they didn't even get a memorial until 2012.
Russia is behaving like it's still the 1940s. 27 Russian soldiers dead for every square kilometre of Ukraine they've taken. They don't value their own lives, and so they certainly don't value those from other countries.
