In The Tell-Tale Heart, the narrator realizes that he lacks a motive for killing the old man he shares a house with. He even admits he loves the man. He states, "I loved the old man. He had never wronged me. He had never given me insult. For his gold I had no desire". Madness is apparent in the unreasonable rationality the narrator uses to justify his murder.
He thinks the desire to murder the old man results from the man's eye, which bothers him a great deal. He writes, "I made up my mind to take the life of the old man, and thus rid myself of the eye forever". Being angered by the man's eye is such an insignificant reason for the narrator to kill him, which proves that he is not mentally stable. His madness is also represented through the planning he put into committing the murder.
Furthermore, when the narrator initially proposes the "vulture eye" as his motive for killing the man, he is not fully certain that this is his reason for committing murder. This indicates that the narrator is completely insane
