Every choice a person makes and every act they participate in results in either a good or bad response. In Macbeth, Macbeth is faced with many serious choices. With this decisions, Macbeth is dealt with severe consequences. Through these decisions and consequences, Shakespeare uses the theme of justice to characterize Macbeth as a very gullible murderer, who is very conscience of what he is doing. Several times in this story, Macbeth is given the opportunity to choose good over evil. For Macbeth, after his first decision to actually believe the witches prophecies, this morality continues to decline and the bad choices follow. The first time the witches speak to Macbeth, they foreshadow that he will become Thane of Cawdor and King of Scotland. Hearing this, Macbeth becomes anxious for the prophecies to come true and takes matters into his own hands. While Duncan is staying in Macbeth's household, the host and his wife confirm the decision to murder the King. Once Macbeth has completed the scheme, he says to his wife, "I have done the deed." After he killed the King, Macbeth covers up his tracks and kills the guards that were watching over the King's chambers. When he is questioned about these murders, he falsely claims that the guards were the ones that killed Duncan. "O, yet I do repent me of my fury, that I did kill them." After these decisions, Macbeth continues to follow this path when he chooses to kill Banquo and his sons to ensure that Banquo's children will not replace Macbeth as King of Scotland. After speaking with the witches for a second time, Macbeth decides to kill Macduff's family because he knows that Macduff has a suspicion that he killed King Duncan. He also knows that the witches warned him about Macduff. "Beware the thane of Fife." After Macduff hears of the death of his family, he vows to get revenge on Macbeth by murdering him. Shakespeare uses the theme of justice most obviously through Macduff's revenge on Macbeth.
