On Killing: The Psychological Cost of Learning to Kill in War and Society

by Dave Grossman

During the months of firebombings and carpet bombings, the German population experienced the distilled essence of the death and injury suffered in combat. They endured fear and horror on a magnitude such as few will ever live to see. This Reign of Fear and horror unleashed among civilians is exactly what most experts hold responsible for the tremendous percentages of psychiatric casualties suffered by soldiers in battle. And yet, incredibly, the incidence of psychiatric casualties among these individuals was very similar to that of peacetime. There were no incidents of mass psychiatric casualties. The Rand Corporation study of the psychological impact of air raids, published in 1949, found that there was only a very slight increase in the “more or less long-term” psychological disorders as compared with peacetime rates. And those that did appear seemed to “occur primarily among already predisposed persons.” Indeed, bombing seemed to have served primarily to harden the hearts and empower the killing ability of the nations that endured it.
