Macbeth If it hadn't been for the three witches, Macbeth would never have killed Duncan nor Banquo. Macbeth, also would not have been killed my Macduff. The three witches are the reason that everything happened the way the they did. In the beginning of the play, the three that Macbeth would become Thane of Cawdor King of Scotland.
In the near future Macbeth became the Thane of Cawdor because of his valiant efforts in the war. Macbeth started to think about the witches to become a little ambitious. With the constant nagging and mockery of Lady Macbeth, Macbeth decides to go through with the murder of Duncan. Thus, another one of the witches prophecies was fulfilled. The witches that Banquo's sons will be kings.
In the worry of Banquo finding out about the murder of Duncan and the thought of Banquo's son, Flea nce, Macbeth hires a to murder Banquo and his son. Later, three ghosts appear in front of Macbeth. First, an armored head appears and warns Macbeth to beware of Macduff. Second, a bloody child appears telling Macbeth that no man born a woman should harm him. Third, a child holding a tree, tells Macbeth that he is safe until BirnhamWoods comes to Dunsinane. After the three ghosts visit Macbeth, the apparition of Banquo appears.
Following Banquo is seven of his descendants, all of which were deceased kings. The first of the three warnings from the ghosts comes true when mac duff allies with Malcolm, one of Duncan's sons. Together they plan to retake the throne of Scotland. Macduff and Malcolm plan to use the leaves and branches ofBirnham Woods as camouflage.
Before Macbeth is killed, he remembers the third ghost that stated that no man born a woman should harm him. Macduff then explains that he he was razed out of his mother's stomach, which means that he was not born a woman. All three of the warnings from the ghosts came true. This is why I believe that if Macbeth had never spoken to the three witches, none of this would have happened.
