A WWII vet, Schultz unit saw combat only at the very end of the war. He was surprised one day when a German soldier suddenly appeared before him. Schultz pulled the trigger on his weapon but had forgot to load it. Fortunately the enemy soldier threw down his weapon and surrendered. It's theorized that the trauma of thinking one second he was going to die and the next second realizing he could have taken another human's life was a nascent force in driving him to create a world of innocence where children played bereft of the meddling of adults.
