The dangers of Montresor's pride are exemplified in his statement explaining his motivation behind plotting Fortunato's death.
"The thousand injuries at the hands of Fortunato I had borne as best I could, but when he ventured upon insult I vowed revenge" (Poe, 173). Montresor is so convinced of the righteousness of his convictions that he "must not only punish but punish with impunity" (Poe, 173). Montresor also states how he must not fail to "make himself felt as such to him who has done the wrong" (Poe, 173). Montresor's words prove how his prideful obsessions have deluded his mind enough to believe that Fortunato's wrongs justify his agonizing death. Furthermore, Montresor believes he should go unpunished for his
retribution.
Furtunato's pride, and the danger this imposes upon his life, is seen in how he blinds himself to his obviously perilous situation. Montresor entreats Fortunato to leave the tombs three times mentioning how Fortunato's cough may be caused by the nitre. Each time Fortunato declines despite his deep cough, which proves how pride has blinded him to his impending doom. However, after Fortunato is locked in his tomb Montresor says "once more let me implore you to return" (Poe, 176) mocking how Fortunato blindly passed up his three chances to escape, because now Montresor "must positively leave" (Poe, 176) him to die. In fact, Fortunato never doubts Montresor's story, never questions why the cask has been placed within Montresor's family tomb, or why the cask is so far into this tomb, and is easily tricked when Montresor mentions that Luchesi can accomplish the same task if Fortunato is not up to it. These actions prove how Fortunato's obsessive need to identify the good wine from the bad confirms that he is as much a fool as his motley suit denotes. According to Cooper "The fool also represents unregenerate man who does not know whence he came or where he is going but goes on blindly towards the abyss" (Cooper, 71).
Montresor's pride manifests itself dangerously through the motto of his family crest, "no one attacks me without paying dearly," reflected in the image of the Montresors' arms: "a huge human foot d'or, in a field azure; the foot crushes a serpent rampant whose fangs are imbedded in the heel" (Poe, 175). The meaning of the crest declares how intolerant the Montresors are of losing face and the lengths they will go to for reprisal. Montresor's literal interpretation of his crest and motto reflect both his pride and need to redeem what was once a great family. Aspects of the crest symbolize why Montresor feels that he must crush Fortunato as the foot on the crest crushes the serpent. The color blue on the Montresors' family crestazurerepresents "the defeat of an enemy" (Cooper, 40). The color gold on the foot represents "immortality and the highest value" (Cooper, 40) and also connects to Montresor, which means "my treasure." The serpent on the crest signifies "death and destruction, life and death, good and evil, wisdom and blind passion" (Cooper, 146). The serpent biting the heel embodies "the vulnerable part of an otherwise invulnerable person, and is also the part which kills the serpent and grinds under evil" (Cooper, 82), providing justification for Montresor's actions.
Montresor's mind, which has become dangerous and poisoned by revenge, reflects how his family's tombs have become dangerous and poisoned by nitre. Revenge has led Montresor to explore the deep, dark, and damp parts of his family tombs, which "no mortal has disturbed" (Poe, 177) for half a century, just as revenge has also led Montresor to explore deep and dark aspects of his own mind, which he has never explored before. The vengeful Montresor easily manipulates the drunk, weakened, and prideful mind of Fortunato into following him down into his family's catacombs, where Fortunato literally walks into his own grave in his pursuit of the "cask" which ends up being his own casket. In the catacombs of Montresor's mind the thousands of injuries he has endured become as dangerous to Fortunato as the nitre. The poisonous nitre, which is formed from the decomposition of dead corpses and represents the past vengeances of the Montresor family, will grow deadlier with the new addition of Furtunato.
Montresor's sanity is in danger with his zealous need for vengeance. Montresor is portrayed as a relatively normal man; however, when Fortunato begins to scream, interrupting Montresor's work, it causes him to hesitate and tremble, and then to physically lash out at something as insubstantial as a noise. "Unsheathing my rapier, I began to grope with it about the recess" (Poe, 177). This action shows how Montresor's tenuous hold on reality and self-control is slipping. This is further shown when Montresor drowns out Furtunado's terror filled screams with his own. "I replied to the yells of him who clamoured. I re-echoed, I aided, I surpassed them in volume and in strength" (Poe, 177), bringing Montresor's grasp on reality further into question. Montresor's deviant, calculating, and poisoned mind is displayed by not only the fact that he will murder but also in the way he does the deed: locking and bricking Fortunato up in a tomb filled with nitre and Montresor's dead family, leaving him slowly to die in darkness. Again the Montresors have effectively grinded the evil serpent into the ground. Montresor's vengeance is complete and the debt owed to him has been paid, and paid dearly.
The dangers of pride and revenge are addressed in "The Cask of Amontillado," a short story by Edgar Allan Poe. Poe utilizes the subjects of pride and revenge to create a horrific and suspenseful masterpiece. Poe reminds us that pride can lead us to do unthinkable things that we would never otherwise consider doing, such as killing in order to get revenge on someone who has crushed our dignity and pride. Pride in excess can cause one to become blinded and oblivious to impending doom, leading a person to dangerous situations and, in the most severe of cases, leading a person to his/her own death. Fortunato dies for his excessive pride, and Montresor is made a murderer because of his.
