They act without consulting her. This is because she is totally irrelevant to the plot, being a later addition probably after Shakespeare's death. So irrelevant is Hecate that her character is systematically cut out of every professional production of this play.
Macbeth killed banquo. Because Macbeth heard the witches say he will also be king. so Macbeth saw him as a threat to the throne and lets just say did something bad to banquo (killed him)
To make sure that Banquo's son wont become king as the witches prediccted.
The first meeting of Macbeth and the three witches serve as an important element for the play and it is from there that Macbeth's decline starts.In fact the third prophecy acts as an instigator for Macbeth and that leads to his downfall.The super hero Macbeth turns into a weakling only after this.It is here that the seeds of overambition gets hold of Macbeth.Had it not been for this meeting Macbeth itself wont be thereIn Shakespeare's Macbeth, the meeting between Macbeth and the three witches serves as the catalyst for the drama. The witches introduce the idea of his being king to Macbeth, or at least make the idea concrete for him. They put fate or destiny on his side.In other words, it is possible that Macbeth had entertained thoughts of being king before he meets the witches. It may even be likely, though there is no concrete or absolute evidence of this. But the witches give him corroboration for his thoughts, if he was having them, and, more importantly, tell him that it is his destiny to be king. That's all Macbeth, and his wife, for that matter, need to begin devising a plan and putting it into action. And this plan, of course, involves killing the present king.The meeting, in foul weather and filled with mysteries (the weird sisters seem to vanish, for example), also furthers the themes of appearance and reality and fair and foul. Throughout the play, people and circumstances are often not as they seem. The theme of the supernatural is also furthered.The problem Macbeth has throughout the play with Banquo is developed here, too--since Banquo is present, he knows the predictions made by the witches, and will therefore naturally suspect Macbeth of treachery when Duncan is killed. And Macbeth knows it. This makes Banquo a threat to him, which will lead Macbeth to order his killing, which leads more and more people to suspect Macbeth.
Macbeth didn't think Macduff was a threat because the witches said "None of woman born shall harm Macbeth." Macbeth welcomes this good news and, assuming Macduff was born the natural way, Macbeth thinks he has nothing to fear.
No, Macbeth killed Macduff's family but not Macduff. Macduff kills Macbeth after telling Macbeth that he wasn't born of a woman; he was born of a C-section or "untimely ripped" from his mother's womb as it says in the play. After Macduff reveals this it appears that Macbeth gives up on fighting because he realizes that it is his destiny to die at the hands of Macduff and then he makes an effort to die an honorable fighting death. Macduff kills and beheads Macbeth off stage, and then he brings Macbeth's head on a pole and presents it to Malcolm the new and rightful king of Scotland.
Lady Macbeth poses the greatest threat to Macbeth in the play as she is the one who instigates his ambition and pushes him to commit regicide. The Witches also pose a significant threat as their prophecies fuel Macbeth's ambitions and ultimately lead to his downfall. Lady Macbeth's manipulation and the supernatural influence of the Witches are the most potent threats to Macbeth's sanity and power.
The witches prophesized that a long line of Banquo's sons will succeed Macbeth in the throne. Macbeth therefore knows that he will not be king forever/his ruling will stop after himself, so he feels that Banquo is a threat.
The apparition of the bloody child represents Macduff, who was born by Caesarean section and is the only one who can defeat Macbeth. The witches are warning Macbeth of Macduff's threat to his reign, as he is the one destined to challenge and overthrow Macbeth.
Macbeth killed banquo. Because Macbeth heard the witches say he will also be king. so Macbeth saw him as a threat to the throne and lets just say did something bad to banquo (killed him)
In Act 3 of Macbeth, Macbeth becomes suspicious that Banquo poses a threat to his throne. He worries that Banquo's descendants will inherit the crown, as the witches prophesied. This suspicion leads Macbeth to plot Banquo's murder.
The witches predict that Macbeth should be wary of Macduff, as he is a potential threat. This comes true when Macduff leads an army to overthrow Macbeth. They also predict that Macbeth will not be defeated until Birnam Wood comes to Dunsinane. This comes true when Malcolm's army uses tree branches from Birnam Wood as camouflage to approach Macbeth's castle.
Ignorance leads to killing Banquo in Shakespeare's play "Macbeth" because Macbeth believes that Banquo's descendants pose a threat to his own reign. Macbeth is misled by the witches' prophecies and allows his fears and ambition to cloud his judgment, leading him to order Banquo's murder in an attempt to prevent the realization of the witches' predictions.
*Banquo. Macbeth's best friend is Banquo, but he is also Macbeth's enemy. After the meeting with the witches, Macbeth finds out that he will become the Thane of Cawdor and the King of Scotland. Eventually, he achieves both of these prophecies. Banquo, Macbeth, and Lady Macbeth are the only people that know about the witches. Banquo becomes suspicious of Macbeth because Macbeth fulfills the prophecy after King Duncan is murdered, and Macbeth acknowledges this fact. Basically, Macbeth doesn't trust Banquo.
The first apparition in Shakespeare's Macbeth is a floating head that tells Macbeth to beware of Macduff. It says that Macbeth should be on guard against Macduff because he poses a threat to Macbeth's reign.
In Act 3 of William Shakespeare's "Macbeth," Macbeth's worst enemy is arguably Banquo. Macbeth sees Banquo as a threat to his newly gained power because of the witches' prophecy that Banquo's descendants will inherit the throne. Macbeth becomes obsessed with eliminating this potential threat, leading to Banquo's murder.
Macbeth is at war with the future that babies and children represent because the witches' prophecies predict that Banquo's descendants, not Macbeth's, will inherit the throne. Macbeth sees these innocent generations as a threat to his own power and is willing to commit atrocities to secure his reign.
Macbeth killed Duncan because the witches predicted that he would be the king but at the time Duncan was the king so in order to be king Macbeth kills Duncan since he was the successor at the time.
