An essay on the role of sadism in human experience. Arguably essential in understanding the Holocaust, and also understanding the events of October 7, 2023. "Fiction" the way ancient Greek mythology is "fiction." An exploration of the ancient predatory behaviors that pre-dated civilisation and re-appear in people whenever civilisation is destroyed. My late father, whose ancestry was from Tomasov and Petrokov, who read the book but did not live to see the film, said the stories were emotionally authentic. My late mother, whose ancestry was from Silesia, who read the book but did not live to see the film, said she grew up hearing these stories, and she thought Kozinski had taken mythology from an older oral tradition reaching back millennia, and then he condensed the horrors into a single narrative. I advise read the book, then see the film. Both the book and the film are masterpieces.
