The bolded part has been said by many people, but I believe it is wrong. Well, it is true, but their targeting of civilians and infrastructure is from the Russian play book. They have been doing it all over and most recently if you look at Syria they especially did it there.
The intention is first that they don't care about bad publicity or people, they just want to win and get capitulation. So while they target fighters, they also intentionally target Hospitals, schools, civilian living places etc. They do this because while it makes people hate the Russians, what they are working to achieve is a point where people say "I'd rather know my kids are safe and we can get medical care and live with these totalitarian assholes in charge, than worry every day about my kids, parents, medical care etc." If they are attacking your country you may support a fight, but if they attacking your ability to help your kids, family and provide them with basic necessities to live and survive then you may stop resisting, and just admit that while the Russians dominating you is a bad option, but it is better than constant fear and death for kids, families etc.
