Even at the beginning of the story, Macbeth was characterized as a violent, brutal soldier, “For brave Macbeth, with his brandished steel. which smoked with bloody execution,” (I,i, 18-20) This trait carries Macbeth throughout the play, and is an essential reason of his tragedy. His vicious mentality drove him to his first of many wrong choices, to kill Duncan. Yes, the witches originally prophesied that Macbeth would become king, but they never stated how he would achieve this goal, “All hail, Macbeth, that shalt be king hereafter!”(I,iii,53).This makes Macbeth responsible for killing Duncan, which marked the start of his tragedy. The witches’ prophecies somewhat partook in influencing Macbeth, but he made the extreme choice of murdering Duncan himself. In addition, Macbeth lets the Witches influence him later in the play. In Act 4, the Weird Sisters summon three apparitions that tell Macbeth of his future. The second apparition, a small bloodied child said.”The power of man, shall none of woman born shall harm,” (IIII,i,91-92). This prophecy gives the already confident Macbeth even more satisfaction because he now believes that he is invincible, since he can’t be killed by a man born of a woman. After hearing this, Macbeth’s leisurely goes into battle without any fear of being killed. Little did he know, Macduff was born of a c-section, and was ready to kill Macbeth. Although the Witches told Macbeth he was “invincible”, Macbeth still had free will, and chose to not only to believe, but follow through on their prophecy and go fight for his place as king.
