Ray Bradbury,
The square pegs
(1948)
“ Taking Lisabeth's pale hand John said, "It didn't work. Come along. Upstairs with you, scheming lady.""What happened?" Alice and Helen waited as he brought Lisabeth up the ladder."They wanted to die," John said, smiling tiredly. "They weren't Killers, but the Ones To Be Killed. I see it all now." He laughed sharply. "To make an insane killer happy, you have to provide him a culture where people like and approve of being killed. This is such a culture. Those men wanted to be shot." ”
