Men are recruited at a psychologically malleable age. They are distanced from their enemy psychologically, taught to hate and dehumanize. They are given the threat of authority, the absolution and pressure of groups. Even then they are resistant and have trouble killing. They shoot in the air; they find nonviolent tasks to occupy them. And so they still need to be conditioned. The conditioning is astoundingly effective, but there is a psychological price to pay.
