As Montresor finishes building the wall, he takes a second to reflect on what he is doing, “…an instant's thought reassured me. I laid my hand on the solid structure of the catacombs, and felt satisfied” (Poe 165), not only does he feel no remorse for what he is doing, but he is proud of having killed Fortunato. Montresor is so fixated on the fact that he considers Fortunato better than him, turning him into a sociopath for killing in cold blood. After Montresor finished building the wall to seal Fortunato Montresor determined, “My heart grew sick from the dampness of the catacombs” (Poe 166). This sick thought is ironic about feeling bad for killing Fortunato, he has never felt bad; despises Fortunato. Even “…half a century” after sealing him there, “no mortal disturbed them. With requiescat rhythm!” (Poe 166), Montresor feels no remorse for killing Fortunato. In fact, he's proud to have walked away from it. Montresor is so enraptured by the impunity of killing Fortunato that he feels the need to tell one of his men about it.
