"...All hail, Macbeth! hail to thee, thane of Glamis! All hail, Macbeth, hail to thee, thane of Cawdor!All hail, Macbeth, thou shalt be king hereafter!
"I have done the deed. Didst thou not hear a noise?"
Absolute power corrupts absolutely
"...Whose absence is no less material to me Than is his father's, "
"Your castle is surprised; your wife and babes Savagely slaughter..."
A Scottish General named Macbeth receives a prophecy of his eventual rise to power as king of Scotland. Consumed by the desire to be king, He begins to think about what must be done to be king.
Macbeth's thoughts become clouded by his thoughts and ambitions. Not to mention his wife who was also power hungry. To be king he would have to do something very drastic, that being that to become king, he would have to kill King Duncan, and so he did in act 2 scene 2.
Macbeth's state continues to worsen. He becomes more paranoid and anxious and orders the murder of Banquo, his 'ex-best friend' also apart of the prophecy, and his son. As said in act 3 scene 1. In the prophecy it is said that Macbeth's successor will be Banquo's son. Therefore giving Macbeth his reason to kill, he wants to stay king and doesn't want anyone to take his title.
At the peak of corruption and paranoia, Macbeth asks for a second prophecy and receives it. It is stated that no woman-born can kill him. Now, you would think that this would stop him from killing anyone else, but as a precaution for him, he orders the death of Macduffs family. Macduff is thane of Fife and is the only one who really suspects foul from Macbeth in the murder of King Duncan. So as stated in Act 4 scene 3 to tie up loose ends, Macbeth murders Macduffs family.
The tone of this theme is dark and corrupt. It shows how a man can go from a kind, and loving person to a hateful paranoid bloke because of power. The tone of this theme really peaked when Macbeth began killing Macduffs family. A man can never be darker and more corrupt than killing a family for power.
