Oh wait I get it.
Azov atrocities have a point. It's to motivate Azov to fight. The more atrociously they behave to Russian prisoners, the more they're afraid of being taken prisoner themselves. Cannot surrender in any form whatsoever.
I'd like to know how intentional this is. Accidental genius, or just what cowards have to do to themselves? Being brave isn't an option, they need to be more afraid of not fighting than of fighting.
