After the death of Duncan, Macbeth begins to distance himself from Lady Macbeth, and he becomes ambitious. Despite being a king, Macbeth is worried about Banquo:
Macbeth fears that Banquo’s son will become king so he finds three murderers and tells them to find Banquo’s son and kill him. Since they are killing his son Macbeth says to kill Banquo. The murderers kill Banquo but not his son. Macbeth throws the murderers into the dungeon. Later Macbeth starts hallucinating. He sees Banquo and is scared. At the end of this act MacDuff escapes.
Banquo, inspired by the witches' prophecy that his descendants will be monarchs; he tries to resist the temptation to hurry the event. Macbeth, does quite the opposite, he takes advantage of the opportunity of the King's visit to his castle. With the help of his wife, they poison the grooms of the King's bedchamber, and stab the sleeping king, to death. When the murder is discovered on the following day, Macbeth shows great grief and anger. To distract suspicion from himself, he kills the grooms as though furious by their denial of the deed. Malcolm and Donalbain, the King's sons, fear and flee the country; and Macbeth, as next in power, is crowned King.
The Emotions of Ambition, Remorse and Fear in Macbeth by William Shakespeare
The most important emotions that we see in Macbeth are ambition, remorse, and fear. They are significant because they provoke Macbeth to do evil and cruel things. Ambition takes control of him earlier in the play when the witches tell him he is going to be king. After he already has done the deed, killed Duncan, he is remorseful for his actions. Out of fear for himself, Macbeth murdered Macduff’s family and killed Banquo.
The Insecurity of Macbeth
Macbeth, the main character in William Shakespeare's tragedy, Macbeth was not secure in his manhood. This insecurity led to the downfall of Macbeth because he felt the need to prove himself to Lady Macbeth. After he proved himself by killing Duncan, Macbeth became desensitized to killing.
In the beginning of the play Macbeth showed his love for Lady Macbeth in many different ways.
Having murdered Duncan, Macbeth fears that Banquo will undermine his ill-gotten authority and destroy his lineage of sons in line to be king. Macbeth and Lady Macbeth, who were both afraid, suspected that Banquo will undermine their authority; and thus their “fears in Banquo stick deep.” This demonstrates why Macbeth is as alarmed about Banquo as “Mark Antony was by Cæsar,” Macbeth compares himself to Mark Antony, and Banquo to Cæsar because Cæsar had beat Mark Antony in battle. Macbeth's words show that he is greatly dismayed and (according to the witches,) his “Barren scepter” will be “wrenched” from his “unlineal hand.” Macbeth believes that Banquo’s sons will be the heirs to the throne, and “wrench” the throne away from Macbeth’s descendents,
Fear motivates many to act upon matters, be they right or wrong. In the play Macbeth it was fear that was the main motivating factor that influenced the outcome of the play. Macbeth was fearful of being caught and having to pay for the wrongs he had done – this led to the murders that followed after the murder of King Duncan. Macbeth's actions were also driven by fear of the witches' prophecies - he was afraid they would come true and tried to stop them from happening. Lady Macbeth, was also plagued by fear as evidenced by the constant washing of her hands, sleepwalking and other similar behavior. This entire play was inspired by fear and what it and do to a person.
After murdering Duncan, Macbeth feels that he needs to kill Banquo. He is afraid that Banquo is going to be a problem for him. He is suspicious that Banquo believes Macbeth had something to do with Duncan's murder, "Our fears in Banquo/ Stick deep; and in his royalty of nature/ Reigns that which would be feared" (3.1.47-49). He plans to kill him, though Banquo has made no direct threat against Macbeth. He speaks of feeling inferior to Banquo, even though he is king. "There is none but he/ Whose being I do fear; and under him/ My genius is rebuked" (3.1.53-55). Banquo is Macbeth's closest friend, he is starting to lose trust in everyone around him.
The Significance of Fear in Shakespeare’s Macbeth
“Fear keeps us focused on the past or worried about the future” (Thick Nhat Hanh). A common emotion such as fear, is most widely accepted as negative, but in contrast, fear can be an emotion that drives people. While fear can be both a positive and negative emotion, it is more widely affiliated with the latter. Macbeth is a play involving a Scottish soldier, self titled, and his meeting with three strange witches, that tell him of a prophecy regarding him, and the throne. and when he Shakespeare shows this negative element of fear through the character’s choices, and their reactions to the situation created by those choices.
Macbeth doesn't want Banquo to be in any part of his life, that's why why he killed him. Now that he's come back as a ghost (he's trembling/scared that Banquo will never leave him alone)
