In Macbeth, by William Shakespeare, the main character Macbeth is obsessed with power. When power is placed in the wrong hands bad actions tend to happen. As Macbeth gains more power, he undergoes a change from a noble warrior to a harsh tyrant. This is shown throughout the play as Macbeth is able to abuse his position of influence and hurt the lives of others. Macbeth’s downfall is caused by his greed for power as he becomes too focused on the witches prophecies, becomes too arrogant, and can never be satisfied with the amount of power he has. In the beginning of the play, Macbeth seems to be the good guy of the play. Macbeth wins the battle for the King and is looked at as a war hero. When Macbeth talks to the witches and finds out from there knowledge that he will become King, he starts to change. By the end of the play, Macbeth is the antagonist and is the complete opposite of himself. Macbeth’s greed for power is so intense that he is willing to kill the King just so he can become in charge. Once in charge, people begin to question his character and actions, such as his friend Banquo. Macbeth becomes so paranoid by what the witches told him that he sent murders after Banquo and his son Fleance. Macbeth begins to focus so much on what the witches say that he decides to go back to the for the second time. When Macbeth doesn’t know his faith. Another way that shows Macbeth’s greed for power is his need for more. Macbeth is never satisfied with what he had. Macbeth makes the mistake of killing everyone to try and gain more power. The more people that Macbeth kills the less power he actually has. For example, when Macbeth kills Duncan, Banquo becomes more suspicious of Macbeth. This makes Macbeth have to kill Banquo so that no one finds out about the murder. This causes Macbeth to break down during the banquet and make more people suspicious of him. The last murder that was caused by Macbeth was on Macduff’s family. This causes Macbeth to lose power because now Macduff wants revenge and is willing to kill Macbeth. The last way that Macbeth was overthrown was because he was way to arrogant. When he talked to the witches the second time, he gets fooled by them. Hecate the god of the witches orders that they trick him and bring his confidence up. Macbeth is grateful for the new prophecy and begins to think that he is unstoppable. “Thou wast born of woman But swords I smile at, weapons laugh to scorn, Brandish’d by man that’s of a woman born.”(5.7 16-18) Macbeth gets fooled and believes that he is unstoppable. Macbeth’s arrogant mindset ultimately seals the deal as he accepts the challenge from Macduff and later dies. In conclusion, Macbeth’s character changes as he is able to gain more and more power. Macbeth’s downfall is caused by that greed for power. Macbeth is to focused on the prophecies from the witches that he becomes so arrogant, and is never satisfied with how much power he has. In macbeth the lesson to be learned is that you should be happy with what you have instead of wanting more to the point that you are willing to change who you are as a person.
