Historically turncoats were always treated without remorse. It was society's biggest taboo up until after WW2. Then they granted conscientious rejectors rights. Because more and more minorities refused. Despite the draft. It kept society honest. It created heroes.

But in a situation like this. It is terrible form. It sooner plays into narratives of opposing war crimes. Despite them being perpetuated here, effectively. Death or death. How low can he go. These people's shared a culture, until he came along. I also understand the past valor and a national cause. There's no retreat. But many want to survive. What I don't understand are the human shields he is using and then holding hostages and demanding ransoms, for an otherwise lost cause, war, there are only Victors.
