Meanwhile compare something like the way Romans waged war: you walk up to someone and you stab him until he stops moving, then you raise your shield to stop the next guy from stabbing you until you stop moving. It's debatably more brutal, but it's comprehensible: you understand what's going on, you understand why the guy on your left just dropped dead. It &quot;makes sense&quot;, it's something that's comprehensible to the human mind and to an extent it's what we evolved to do.
