I think the average Russian citizen does value human life, and I don't judge all of them by what Putin is doing. Many Ukrainians have family ties to Russia, and vice versa. What Putin did is like the UK invading Ireland, or the USA invading Canada or Mexico.
Soldiers do what they are ordered to do, I am not excusing what the car-crushing tank did, but maybe that was a "less-bad" option than crushing occupants. Tank driver may have faced harsh punishment (court martial) if he took no action. I didn't see the video, so can't give an informed opinion, I'll admit. OK, nevermind, found the video, that tank driver deserves whatever the Ukrainians can dish out.
