With the hyperbolic first words, "The thousand injuries of Fortunato I had borne as I best could.." followed by the detailed three-step requirements for perfect revenge, the reader is alerted to the instability of Montresor and the possibility of dangerous repercussions with his plan of revenge against the ironically-named Fortunato:
- Montresor plans not only to avenge himself, but to seek his revenge "with impunity"; that is, without punishment. Therefore, he has planned his revenge with precision.
- The revenge must not overtake Montresor; that is, the revenge must not come back to harm him.
- Montresor insists that his victim must be made aware that he is avenging himself.
With such a well-thought out and cruel plan, the reader suspects that Montresor's plans against Fortunato will be brutally cruel and absolutely final. And such is the case because Montresor at the end states,
For the half of a century no mortal has disturbed them. In pace requiescat
Thus, Montresor ends with an ironic note in saying, "May he rest in peace" while also underscoring his three-point plan of revenge in which he has punished his enemy without being caught, he is not disturbed by what he has done, and Fortunato has been made well aware of his victimization by Montresor.
