At some point you grow numb to this.
There's only so many times you can ride into a village, kill the men, enslave the women, burn the houses, and do all the things that the Leader needs us to do to win the war. Eventually you stop seeing them as people, stop seeing them as families and communities. Eventually they are vermin to be eradicated, a plague to be dealt with, a simple problem with a simple answer of the blade, the flame, the righteous fury.
At some point you grow numb to it all.
Right? Eventually? Hopefully really soon?
