Indirectly, perhaps. Macbeth killed Duncan because Lady Macbeth manipulated him into doing it, and she did that because he had told her about the witches' prophecies.
Macbeth kills King Duncan because he is manipulated and influenced by the witches' prophecies, particularly the prediction that he will become king. While the witches' predictions play a role in triggering Macbeth's ambition, ultimately it is his own choices and actions that lead to Duncan's murder.
The witches only gave Macbeth prophecies. It was his decision to do so after Lady Macbeth persuaded him. Although the witches' intentions was probably to cause this murder, the witches did not make Macbeth muder Duncan.
The letter of Macbeth was important to Lady Macbeth. It reinforced for her that the two worked together as a couple. Her husband confided in her, and respected and depended upon her advice and guidance. He didn't just tell her that they'd have the honor of King Duncan I as their house guest at Inverness Castle. He also updated her on his interactions with the three witches and their predictions of ever greater things for him on the job. Because she was warned in advance of the visit and of the predictions, she could prepare her household for her guest and her victims.
MacBeth tells Banquo that he had not been thinking of the witches after Banquo says he, himself, has. Banquo is thinking about the predictions and MacBeth becoming Thane of Cawdor fulfilling one of the prophesies. This occurs after MacBeth is set on killing Duncan, the king. He is trying to hide his guilt even before he is truly guilty.
He kills the chairman, and he admits it saying he did it out of rage, scaring Duncan's sons more.
Macbeth wanted to kill Banquo and his son because he feared that they were a threat to his throne. The witches had predicted that Banquo's descendants would inherit the throne, which posed a risk to Macbeth's own lineage. By eliminating Banquo and his son, Macbeth believed he could secure his power.
He should tell himself that it is not his fault because as the three witches prophesied, it is fate and fate is inevitable.
It's likely that Macbeth would not have killed Duncan if the witches had not planted the idea of his kingship in his mind. While Macbeth struggled with ambition, the witches' prophecy ignited and intensified his desires, leading him to take action. Without the witches, it's possible that Macbeth's fate would have unfolded differently.
The three witches in the beginning of the play told Macbeth that he will be King. And his own ambition pretty much lead him to kill Duncan. *Lady Macbeth also has an influence in the murder of Duncan*
After MacBeth receives the predictions from the witches he writes a letter to Lady MacBeth detailing the whole situation. He calls her his "dearest partner of greatness" and is very trusting of her. He is also subject to much influence from her since she is the one who later convinces MacBeth to kill the king, Duncan, when he is resolute on not doing anything of the sort.
in Shakespear's play Macbeth ,Macbeth becomes the thane of cawdor so its saying kinda all bow to Macbeth This is from the witches predictions. At this point Macbeth is the thane of Glamis, meaning he is the lord of a place called glamis. When the witches say all hail to thee thane of cawdor, they are predicting that Macbeth will be the thane of cawdor. Shalt be King Hereafter-- witches predict Macbeth will become King
