In the play MacBeth written by "William Shakespeare" shows the deterioration of MacBeth and Lady MacBeth's conscience. At the beginning of the play Macbeth is seen as a courageous soldier who is loyal to the King but is corrupted from the witches prophecies and by his and Lady Macbeth"s ambition. This is because of the weakness of Macbeth"s character and the strong power of Lady Macbeth and how she is easily able to influence him. Her strength motivates him at the start but after he realizes what he has done it is himself that continues in his murderous, bloody path. Macbeth is a strong soldier in the start, but his strive for ambition and his curious nature lead him and his wife into an evil and corrupt life.

             In the beginning of the play Macbeth is a strong soldier who fights for the King without mercy but his strive for ambition and his curious nature leads him to the witches who give him a prophecy. Banquo realizes that there must be a trick hidden in the witches prophecies somewhere but Macbeth refuses to accept that, and when Lady Macbeth finds out about the witches her strong desire for ambition and her cold nature leads Macbeth astray. Macbeth is a little ambitious at first, but Lady Macbeth"s far exceeds his and so she is able to get Macbeth to agree with her to kill King Duncan. Macbeth still has a good conscience at this stage because he is very hesitant about killing the King but his weak nature overcomes him. He has an uncertain conscience throughout the entire play as the hallucinations of the dagger and the ghost of Banquo and his vivid imagination see this and his constant worry also provokes him. Even those who appear good and trust worthy can easily become sinister. .

             Lady Macbeth seems to be almost opposite compared to that of Macbeth in physical and mental power. Lady Macbeth is the person who is able to persuade Macbeth into killing Duncan, assuring Macbeth that it will succeed, as Lady Macbeth"s ambition is far greater than that of Macbeth.
