In Shakespeare's Macbeth, the three witches played a vital role in Macbeth's destruction. The three sisters first fuelled Macbeth's ambition by telling him he would one day be hailed King of Scotland. Having no control over his ambition, Macbeth visited the three sisters in search of information about his future. The sisters told Macbeth what he wanted to hear, but did not tell him of the underlying dangers of the Apparitions. The witches contributed to Macbeth's boldness, overconfidence, and finally his destruction. If Macbeth had done what he knew was right, and followed his own ambition, he would have remained loved and respected throughout the play.
Macbeth made many bold moves after hearing the witches tell him that he would one day be Thane of Cawdor and King of Scotland. At first Macbeth was skeptical, but that quickly changed when Macbeth heard of his new title as Thane of Cawdor. When Macbeth's desires got the better of him, he made a very bold move; he killed Duncan. "I have no spur/ To prick the sides of my intent, but only/ Vaulting ambition, which o'erleaps itself/ And falls on th' other ""(I, vii, 25-28). Macbeth acted solely on his own ambition. He tried to take the witches' prophecy and speed it up instead of letting it go through its natural course. .
After the murder of Duncan, Macbeth believed that Banquo was suspicious of him. Macbeth once again made a bold move without thinking about the consequences. Macbeth got two men to murder Banquo so that Banquo could not harm Macbeth's success as king. Macbeth made many moves that could have easily harmed his own success; the murder of Banquo included. Macbeth also remembered that the witches told him that Banquo's sons would someday be king. He told the murderers to kill both Banquo and his son, Fleance, so that Banquo's future relatives would not be crowned. Macbeth misunderstood much about what the three sisters said, and he disrupted the prophecies by trying to speed the process up.
