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

by Dave Grossman

Modern armies have similar mechanisms of purification. In WWII soldiers en route home often spent days together on troopships. Among themselves, the warriors could relive their feelings, express grief for lost comrades, tell each other about their fears, and, above all, receive the support of their fellow soldiers. They were provided with a sounding board for their own sanity. Upon reaching home, soldiers were often honored with parades or other civic tributes. They received the respect of their communities as stories of their experiences were told to children and relatives by proud parents and wives. All this served the same cleansing purpose as the rituals of the past. When soldiers are denied these rituals they often tend to become emotionally disturbed. Unable to purge their guilt or be reassured that what they did was right, they turned their emotions inward. Soldiers returning from the Vietnam War were victims of this kind of neglect. There were no long troopship voyages where they could confide in their comrades. Instead, soldiers who had finished their tour of duty were flown home to arrive “back in the world” often within days, and sometimes within hours, of their last combat with the enemy. There were no fellow soldiers to meet them and to serve as a sympathetic sounding board for their experiences; no one to convince them of their own sanity.
