In “The Cask of Amontillado” foolishness and folly can cost you your life. The story amplifies human foolishness and folly to extremes so hideous and cruel they become vices. ”The Cask” only has two characters. By the end of the story, their combined silliness culminates in tragedy and pain for them both. The tragedy is what makes us think more profoundly about their foolish ways – in the hopes that we can avoid ending up, even in some metaphorical way, like them.
Montresor is the real fool in the story.
