You can't break a man the way you break a dog or a horse. The harder you beat a man, the taller he stands. To break a man's will, to break his spirit, you have to break his mind. Men have this idea that we can fight with dignity, that there's a proper way to kill someone. It's absurd. It's anesthetic; we need it to endure the bloody horror of murder. You must destroy that idea. Show them what a messy, terrible thing it is to kill a man, and then show them that you relish in it. Shoot to wound, then execute the wounded. Burn them. Take them in close combat. Destroy their preconceptions of what a man is and you become their personal monster. When they fear you, you become stronger. You become better. But let's never forget: it's a display, it's a posture, like a lion's roar or a gorilla thumping at its chest. If you lose yourself in the display, if you succumb to the horror, then you become the monster. You become reduced; not more than a man, but less - and it can be fatal.
