Trace Macbeth's Decline into Evil and assess what he has become.

Macbeth doesn’t want to kill King Duncan because he knows it wouldn’t be a worthy kill, not honorable like the person that he is. The only way that he is persuaded to do it is by Lady Macbeth who challenges his man hood calling him a coward and asking if it  “ Wakes now to look so green and pale”. She is the only one who could persuade Macbeth because he dosent want to be called a coward or look like one and lady Macbeth knows this.  We do not actually see Macbeth murder Duncan, but before the murder he has a vision of the dagger leading him on. The fact that such a great warrior and killer of men is so lost in terrifying guilt indicates the full extent of the evil he has committed. Macbeth is so guilty that he can't say "amen".After murdering Duncan, he returns to Lady Macbeth in a distraught, emotional state. He also stupidly brings back the murder weapons. She questions him but he is too frightened to replace them on Duncan's drugged guards. Instead, Lady Macbeth goes and smears them with blood and guilt. Macduff and Lennox arrive. Macduff finds Duncan murdered and the alarm is sounded. Macbeth slays the guards in mock fury as the main suspects. Macduff challenges Macbeth's action in killing the guards and Macbeth says that he couldn’t bear the killers of King Duncan being in his house and anger took over as Macbeth Macbeth says that not even all the oceans in the world could clean his hands showing how much he really regrets killing king Duncan.

So far Lady Macbeth has been dominant. In act 3 scene 2. Macbeth is keeping himself to himself and not telling her the crimes committed, and on the crimes he intends to commit, Macbeth has a very changed image. "O, full of scorpions is my mind. He is not sharing his thoughts with his "dearest partner of greatness". He himself will be the lead role in all of his killings to come showing that Macbeth and Lady Macbeth’s role have switched.
