This is incorrect. The Russians are more or less indiscriminately bombing the cities of Ukraine.

Shows just the opposite. This looks VERY similar to our bombing of Baghdad under “shock and awe.” Looks like they are hitting about one block, NOT all over the city.
If the Russkies wanted to vaporize Karkov, they could have done it yesterday. This looks highly controlled, likely a coms target there.
