Pride carries different verdicts across history: Dante calls it the "Chief of All Sins," the sin that damned Satan himself, while Socrates and the Bible condemn it as a moral failing, and the Romans and Vikings prize it as a virtue worth boasting about. This episode traces how pride ended up on humanity's list of worst behaviors, tracing the seven deadly sins back to a fourth-century monk's original eight-item catalog of temptations, later trimmed to the seven still recognized today. It walks through how the Catholic Church turned that list into a roadmap to salvation, complete with specific punishments for repeat offenders in the afterlife, gluttons force-fed rats, toads, and snakes among them. Against that backdrop, the film asks what made pride different: a sin the Church feared enough to rank first, yet a trait entire warrior cultures built their identity around. It moves between religious doctrine, philosophy, and cultural history to show how the same impulse toward self-regard is both mankind's oldest warning and its oldest boast.
