It’s almost like one side is arresting specific people with handcuffs and eventually pressing actual charges instead of sending in a giant group of people to abduct as many people as possible.

Eh, there is some evidence of it occurring here and there. I think I have seen like 5 or 6 of Ukrainians torturing or killing POWs. If you want, I can go get some links to videos and news articles. It’s pretty rare and seems way more prevalent on the Russian side, who have filmed themselves committing some truly barbaric things, including emasculations and decapitations.
