Or with only a light supervision, when you're not thinking too hard about it, e.g., with one person supervising many of them, and not caring too much about killing human shields. We're already quite desensitized when we explode buildings by simply pressing a button, "not our responsibility".
But of course the real barbarians are those who 'commit suicide'/'take their own lives' when killing 1% of our body count.
Also internally, tyrans fall when their police&army abandon them, some will be pleased.
The good thing is that perhaps, with enough decades, both sides will only use machines and wars won't ever kill humans again. One could hope i guess.
