In Act 2, scene 1 of Macbeth, Macbeth demonstrates a frame of mind of obsession and ambitiousness through the words used in the soliloquy. Throughout the soliloquy, Macbeth portrays obsession over murdering King Duncan for power and obsession to soften his crime. Shakespeare indicates his obsession using diction. Obsession means a state in which someone thinks about something constantly especially in a way not normal and usually comes along with symptoms such as anxiety. Obsession can be seen when Macbeth states that he is getting a “fatal vision” (36) and a “false creation” (38). Due to Macbeth’s obsession, Macbeth sees false hallucinations. His hallucination is fatal because he will use the dagger to kill Duncan. He has created a false creation in his mind to try to convince himself that what he is doing is not going to be his fault; instead the crime was the knife’s fault because the knife was calling out to him. When Macbeth calls the knife an “instrument” (43), he is calling the dagger as a tool to gain power than a weapon to harm. He wants to justify and alleviate his crime as just an obstacle he must pass to reach his dream. When Macbeth calls the murder “business” (48), he is trying to make the crime not personal and indicate that he shouldn’t feel any guilt. Macbeth is using these words to soften his guilt to get rid of his anxiety about the murder. Macbeth exhibits ambitiousness when he used the word “marshall’st” (42). Marshall’st means that he was pushed into the crime in a military manner. By using marshall’st, Macbeth indicates his inner desire, recklessness and confidence in doing the crime. Shakespeare also uses imagery to reveal Macbeth’s obsession and ambition. When Macbeth “mov[ed] like a ghost” (56), Macbeth was cautious and circumspect in accomplishing his goal, and him having the state of mind to be quiet at that time shows that he was prudent in planning and imagining for what he was going to do in the crime. He was overcome with the thought of murdering Duncan that he was planning the crime in a perfect manner without even knowing it. Also, the “gouts of blood” (46) on the knife foreshadows how ambitious and reckless he was going to be in his murder. He could’ve stabbed him once, but the gouts of blood indicate him imagining of stabbing Duncan several times than needed that will create gouts of blood. At the end, Macbeth is compared and described as a “wolf” (53). He is described as a wolf because Macbeth was thirsty of power like a wolf is thirsty of blood and Macbeth “tears” through the castle and obtains the role of the king. Macbeth being compared to wild and vicious animals like a wolf exhibits how Macbeth became because of his obsession of power and ambition to get what he wants.
