This shows his feeling of guilt when passing by the guards after murdering Duncan. Eventually he grows as a king, but not necessarily in a good way. He becomes barbaric in his habits and jealous of Banquo, whom he sees as a threat to the throne. He has Banquo killed and is plagued with a guilty conscience and visions of Banquo's ghost. After he killed Banquo, he becomes a "pro" at the killing scheme to get what he wants and ends up killing Macduff's family, showing how far into his lust for power he will venture. He does this out of fancy, not out of necessity. " At least we will die with harness on our back." (Vvii, Ln 52) This foolish act of dictatorship led to his doom at the hands of Macduff; nevertheless, he faced his end with bravery and valor, completing his cycle by returning to the ways of an honorable warrior.
Another dynamic character in the play that showed immense change in character properties is Lady Macbeth. From first word of the witches prophesies, she was lustful for the power, but doubting of Macbeth's capabilities to be a ruler. She was definitely the manipulator to Macbeth and guided his hand in the murder of Duncan, while convinced of her total innocence. She did display some inkling of compassion towards Duncan when she could not commit the murder herself. "Had he not resembled my father as he slept, I had done't." (Iiii, Ln 11-13). She only had a loving relationship with Macbeth after he had killed and taken some charge to make her queen. Through the tale she seems to be convincing herself that she is liberated of any guilt, while she presumably would be seeing the ghost of Banquo the same time as Macbeth. After Duncan's murder, she tells Macbeth just to wash his hands and go to bed, as if to wash his hands of the deed, but in truth it is her that is incapable of washing herself of the deed. The guilt, which she kept inside, is what eventually destroys her in the denouement when Macbeth's castle is invaded.
