There is no doubt that Montresor was the antagonist of "The Cask of Amontillado". The reader discovered that when reading about his revengefulness at the beginning of this short story. Montresor had enough with Fortunato's insults and finally decided to see an end to his life (The reader inferred that Fortunato had done something to Montresor and/or his family to upset him).
