The disaster of Macbeth mainly revolves around one person, Macbeth. Although other external conflicts influenced Macbeth to begin his killing spree, most of the murders are committed by Macbeth. The witches and Lady Macbeth were the ones who pushed him down his path of self-destruction, but Macbeth ultimately decided to do the evil deed of killing Duncan himself. Macbeth's meeting with the three witches is what first triggered disaster when they told him that he will be lord of Cawdor and king of Scotland. Macbeth is surprised by this news and wants to know more. Macbeth writing to his wife about his encounter with the witches also proved to be a mistake because she became ambitious about Macbeth becoming king and her becoming queen. Macbeth had outside influences involved in Duncan's death, but the other deaths in the play are caused by Macbeth alone. Macbeth was also responsible for the death of Duncan's guards when he said, "Oh, yet I repent my fury, that I slew Them." (A2, S3, 100-101) He had no reason to kill them but his anger allowed him to be irrational. When Macbeth began to suspect that Banquo knew he had killed Duncan, Macbeth ordered him and his son Fleance killed. Banquo was killed and Fleance fled, which confirmed the witch's prophecy that Banquo's future would not be happy and that his offspring would become kings. Macbeth showed his true wickedness when he ordered Banquo and his son to be killed. He demonstrated that he had the ambition to act in a way that protected his lust for power by maintaining the throne of Scotland. When Macduff fled to England, Macbeth ordered him to do so
