the narrator is related to the old man is revealed when the narrator says, "For his gold I had no desire" (Poe, 3). By stating that he does not desire the old man's gold, the narrator suggests that there will be an opportunity for him to inherit the gold in the future. In order for the narrator to inherit the gold, he would have to be a son, nephew, or grandson of the old man, which are all likely possibilities. There is also the implication that the old man would not trust his gold around a servant and would feel more comfortable in the house with a relative. The fact that the narrator only refers to his victim as the old man further complicates matters and contributes to the ambiguity of their relationship. The most accurate conclusion is that the narrator is the old man's grandson or nephew, who is acting as his caretaker.

The narrator does say that he loves the old man.

Object there was none. Passion there was none. I loved the old man. He had never wronged me. He had never
given me insult. (p. 4)

However, the narrator is not quite sane.  He may have liked his roommate's company, but he killed him all the same.

There is no evidence that the narrator is the old man’s servant, other than the fact that the old man had gold. 

For his gold I had no desire. I think it was his eye! yes, it was this! He had the eye of a vulture—a pale blue eye, with a film over it. (p. 4)

This does not imply that the narrator was his servant.  They seem to be roommates.  The old man seems somewhat afraid of the narrator, and if he was his servant wouldn’t he have fired him?

I had my head in, and was about to open the lantern, when my thumb slipped upon the tin fastening, and the old man sprang up in bed, crying out—“Who's there?” (p. 4)

I think if he had a servant in the house, he would have reacted differently.  He might have called his servant, for example, or asked if it was him and ordered him out.

When the police come, the narrator does not introduce himself as a servant.  He says that the old man is not there, but that does not imply that he works for the old man

The old man, I mentioned, was absent in the country. I took my visitors all over the house. I bade them search—search well. I led them, at length, to his chamber. I showed them his treasures, secure, undisturbed. (ch 6)

It is fine to propose theories and look for evidence to support them.  There is no evidence to suggest that the narrator was not his servant, perhaps, but there is also none to suggest that he was.

After planing the seemingly-perfect murder, the author executes his plan, murders the old man, and disposes of the body. We realize that he had no particular feelings of any kind toward the victim; he didn't hate the old man, nor did he like him. He is completely neutral and killed him with no particular reason.

After that, however, instead of feeling some sort of twisted, morbid fulfillment, he feels immense guilt and regret. He tries to calm down, but he fails, and he begins to hear a faint thumping sound in the distance. Confused and a bit paranoid, the murderer begins to think that the faint rhythmic sound he hears is, in fact, the old man's heartbeat. He panics and confesses to his crimes.

In "The Tell-Tale Heart," the narrator makes it clear from the beginning that his feelings towards the old man are warm and positive:

I loved the old man. He had never wronged me. He had never given me insult.

Moreover, the narrator feels no jealousy towards the old man's money or his material possessions. The narrator does, however, grow to dislike the old man's eye. In fact, the eye fills the narrator with "fury" and he describes it as "evil" and animalistic:

He had the eye of a vulture --a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold.

Over time, the narrator realises that killing the old man is the only way to rid himself of the eye. After convincing himself that murder is the only way to proceed, the narrator plots his crime for seven nights - all the while acting kindly to the old man by enquiring after his health and wellbeing. He does this so as not to arouse any suspicion and, on the eighth night, he is finally able to commit the murder. 

In Edgar Allan Poe's Gothic short story "The Tell-Tale Heart," the narrator explicitly states only that "I was never kinder to the old man than during the whole week before I killed him." Nevertheless, the reasons why the narrator was kind to the old man during that week can be inferred from the rest of the story.

Early in the story, the notably unreliable narrator says that he loves the old man. The old man never wronged him or insulted him, he says. The narrator seems to have no ill feelings towards the old man, except that he's obsessed with the old man's eye, "the eye of a vulture," that makes his blood run cold and which caused him to make up his mind "to take the life of the old man, and thus rid myself of the eye forever." The narrator seems not to have any regrets or even second-thoughts about killing the old man, He simply needs to bide his time until the old man opens his "Evil eye."

The narrator commends himself to the reader on "how wisely [he] proceeded[s]," and on his "caution," "foresight" and "dissimulation." These words appear in the sentence directly before the narrator tells the reader that he was never kinder to the old man, and these words offer the reader some clues into the narrator's motivation for being so kind to the old man.

The stealth of the narrator's spying on the old man as he sleeps implies that the old man is a fairly light sleeper, and that he's sensitive to the slightest sound or disturbance in his environment. This observation is borne out when the old man "moved on the bed suddenly, as if startled" as the narrator opened his bedroom door "little by little" on the eighth night. A moment later, the old man sits bolt upright in bed and cries out "Who's there?" at the slightest sound of the narrator's thumb slipping on the lantern's fastening.

Accordingly, the narrator must plan well ahead, using his "foresight," and proceed with extreme "caution" once he puts his plan into action so as not to alarm the old man.

In order not to raise the old man's suspicions and to deflect the old man's attention from his nefarious plan to kill him, the narrator "dissimulates," which is to say that he treats the old man kindly—kinder than he's ever treated him before, he says—in order to give the old man a sense of well-being in the house and to lull the old man into a false sense of security. The narrator tells the reader that he does this by going boldly into the old man's room every morning after the first seven nights of spying on him, speaking "courageously" to him, "calling him by name in a hearty tone, and inquiring how he has passed the night."

However, once the narrator sees the old man's "vulture eye" revealed by the "simple dim ray" of the lantern, the narrator drops all pretense, "leap[s] into the room...pull[s] the heavy bed over him," and waits for the "hellish tattoo" of the old man's beating heart to stop.

The narrator does claim to have loved the old man. So, it would be logical for him to be remorseful after killing him. But the narrator is mad (crazy). He claims that his alleged madness is simply an overly acute attention to sensations and detail. Just before killing him, the narrator senses the old man's terror and expresses pity but also light amusement: 

I knew what the old man felt, and pitied him, although I chuckled at heart. 

When the narrator begins to kill the old man by dragging him to the floor and smothering him, he (narrator) "smiled gaily" to know that he was going through with killing the old man. After the old man is dead, the narrator was not really remorseful nor was he smiling or amused. He is momentarily relieved that he no longer has to feel the gaze of the old man's eye; then he goes into an anxious mode. He dismembers the body in order to hide it. He again notes that this is precaution, not madness. He brags about his precision in hiding the body. 

When the police arrive, the narrator smiles to hide his guilt. After feeling that he convinced them of his innocence, the narrator feels relieved, "I was singularly at ease." However, his conscience gets to him and that momentary relief once again changes into precaution to anxiety to terror when the sound of the heartbeat increases.

So, after killing the old man, the narrator feels momentarily relieved, then anxious, momentarily relieved again, then anxious again and finally leading to complete terror resulting in his confession. 

In the opening paragraph, the narrator tries to convince his listener that he is not mad (crazy). He admits to having a disease but he claims that the disease has made his senses sharper. We have a narrator who claims to be reliable but his anxious insistence makes him seem crazy indeed. It therefore comes as no surprise when he says that he loves the old man but then endeavors to kill him. 

The narrator says he loved the old man, the old man had never wronged him, and that he did not covet the old man's money ("gold"). Illustrating his mental instability, the narrator claims that it is the old man's eye that drives him to insane thoughts. 

I think it was his eye! yes, it was this! He had the eye of a vulture—a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees—very gradually—I made up my mind to take the life of the old man, and thus rid myself of the eye forever. 

From here, the narrator again tries to prove his sanity by describing how strategically he went about killing the old man. But what was it about the eye that drove him to murder? 

The narrator claims that it is not the man himself who he has the problem with. It is only his eye, his "Evil eye." The narrator clearly has some insane, superstitious notion that the old man's eye is evil and is therefore some kind of threat to him. Approaching the old man, the narrator describes his unreasonable fear and terror of the eye: 

It was open—wide, wide open—and I grew furious as I gazed upon it. I saw it with perfect distinctness—all a dull blue, with a hideous veil over it that chilled the very marrow in my bones; but I could see nothing else of the old man's face or person: for I had directed the ray as if by instinct, precisely upon the damned spot. 

The narrator has a self-destructive impulse. If it is not suicide, it is the desire to commit the murder and then be caught. Indeed, this does occur. The guilt manifests when he hears the man's heart beating through the wall. Note the pun of "eye" and "I." In killing the "eye," the narrator symbolically wishes to destroy himself as "I." So, part (or perhaps all) of his desire to destroy the old man's "Evil eye" is actually a subconscious attempt to destroy himself. 

The Tell Tale Heart, is one of Edgar Allen Poe's most famous works. It is a classic tale of how one man's hidden ugliness, can't stay hidden forever. The narrator of the story is insane. We can clearly see this from the very first lines of the story.

The narrator does not hate the old man. He actually feels sorry for him, and pities him. The narrator has a hidden madness on the inside of him. He tries his best to control it, however he thinks the old man can sense it. The old man has one eye that is blue and looks like it has a veil over it. This sounds like the old man had some kind of eye disease. The narrator believes that, since the old man has the blue eye, he can see the inside of someone's heart. He calls it the evil eye. The narrator didn't want to kill him, but since he thinks the old man can "see" his evil, he has no other choice. For seven nights, the narrator sneaks into the old man's bedroom, at midnight, to spy on him. On the eighth night, as he is planning on killing him, he thinks he can hear the old man's heart beating. He kills the old man and dismembers him, hiding the body parts under his floor. He now thinks that he can be in peace. As you know, the beating of the old man's heart is his undoing. 

The narrator of this story is truly an insane person. Thinking the old man's diseased eye allows him to see inside his own soul, drives him to the edge of insanity. The narrator's own guilt about killing the innocent old man, pushes him to a confession. This is probably one of my favorite stories by Edgar Allen Poe. He shows us how far a guilty conscience can push us. He also shows us how far insanity can ruin our lives.

I believe you are somehow confusing William Golding's novel, Lord of the Flies, with the classic Edgar Allan Poe short story, "The Tell-Tale Heart." In Poe's short story, the narrator is more kind than usual to the old man with the "vulture eye" because he wants to lull him into a feeling of security before killing him. It may also involve a guilty conscience about the murder he is about to commit.

There are no adults in Lord of the Flies until the end when the surviving boys are rescued.

The unreliable narrator of Poe's classic short story "The Tell-Tale Heart" attempts to convince his audience that he is sane as he elaborates on how he plotted and killed the unsuspecting old man. After assuring the audience of his mental stability and sanity in the first paragraph, the narrator describes his motivation for killing the old man in the second paragraph. The narrator mentions,

Object there was none. Passion there was none. I loved the old man. He had never wronged me. He had never given me insult. For his gold I had no desire. I think it was his eye! (Poe, 1)

The narrator goes on to elaborate on the old man's pale blue eye, which haunts and disturbs him. It is important to remember that the narrator is attempting to convince the audience of his sanity and claims that he has a "disease," which gives him the ability to hear all things in heaven and hell. By mentioning that he loves the old man while he is simultaneously plotting to kill him, Poe is revealing that the narrator is unreliable and mentally insane.

The narrator feels that is necessary to emphasize the disturbing, unsettling quality of the old man's vulture eye because it is his prime motivation to commit murder. By insisting that he loves the old man, the narrator is establishing that the Evil Eye is the sole reason he desires to kill the old man. The audience recognizes that the narrator's motivation is ridiculous and is further evidence that contributes to their belief that he is insane.

In “The Tell-Tale Heart,” the narrator, who claims to be sane but whose actions demonstrate otherwise, decides to kill the old man he takes care of.

The narrator says he does not have any ill feelings toward the old man, nor does he have any interest in his money. He decides to kill the old man simply because he is unnerved by his vulture-like eye.

The narrator proudly tells us how carefully and methodically he planned the old man’s murder. During the week prior to the killing, the narrator is exceptionally kind and loving toward the old man. He says, “I was never kinder to the old man than during the whole week before I killed him.”

The narrator, who is clearly insane and suffers from an unspecified disease, is unreliable, which makes his behavior and motivation difficult to discern. There is a lack of alignment between his words and his actions. For example, he claims to love the old man but devises and carries out a plan to kill him. Similarly, the narrator frequently tells us he is not insane, while engaging in obviously insane behavior.

It cannot be known for sure why the narrator is extra kind to the old man in the week preceding the murder, but it is likely that he behaves this way to avoid arousing the old man’s suspicion. Perhaps he wants to kill the old man quickly and suddenly and spare him the foreknowledge of his death and the fear that would accompany it. Perhaps he does not want the old man to have a chance to fight back or thwart his insidious agenda. Another possible reason for the narrator’s kindness is guilt. Perhaps, on some level, he feels guilty for planning to kill someone who has been kind and good to him.

Poe's intentional ambiguity leaves us to draw our own conclusions about the narrator's behavior.

The narrator of "The Tell-Tale Heart," who, like most of Poe's narrators, is thoroughly unreliable, claims to have loved the old man. (That would be the old man whom he brutally murdered. Imagine what he'd have done if he'd hated him!)

The old man was always kind to the narrator; he never once did him wrong or insulted him in any way. Yes, he had this weird eye which made the narrator nervous—so nervous, in fact, that it caused him to kill the old man—but other than that, he was a stand-up guy. And because the old man was always so incredibly kind toward him, the narrator never had the slightest desire for his gold.

Once the narrator has resolved to kill the old man—so that he won't have to be spooked by his evil eye ever again—he tries to lull his intended victim into a false sense of security. He does this by acting kindly toward the old man (indeed, more kindly than he's ever acted before) in the week leading up to the murder.

Every night of that week, the narrator creeps into the old man's bedroom but is unable to carry out the deed, as the old man's evil eye remains closed. But this gives the narrator the opportunity to continue lulling the old man into a false sense of security by inquiring how he slept the following morning, giving the impression that the narrator was concerned and wanted to make sure that the old man got a good night's sleep.
