The theme of revenge in “The Cask of Amontillado” is the driving force for the entire short story. The main character, Montresor, vows to take revenge against the other main character, Fortunato, because of an “insult” that Fortunato has apparently made against Montresor (Baraban). This is evident in the opening line of the short story when the narrator Montresor states, “The thousand injuries of Fortunato I had borne as I best could, but when he ventured upon insult I vowed revenge (Poe 1612). This opening line makes it obvious that the insult is what directly led to Montresor’s insatiable desire for revenge, but there are also some underlying factors that could have indirectly led to this revenge as well. The first indirect factor that could contribute to Montresor’s vengeful act, and thus the story’s theme of revenge, is the character of Montresor.
