Agh Macbeth, thy come to haunt you again for a second time!
Unfortunately, indeed. I thought to myself: "Why hath it given me earnest of success,/Commencing in a truth? I am the Thane of Cawdor./If good, why do I yield to that suggestion/And make my seated heart knock at my ribs,/Against the use of nature? Present fears/Are less than horrible imaginings" (1.3.133-140).
No! I know all now and must keep you from doing more harm! Once you heard the witches' prophecy, your relentless ambition was born. So, didn't you wish to kill the king?
I felt that, "I have no spur/To prick the sides of my intent, but only/Vaulting ambition, which o'erlaps itself/And falls on th' other" (1.7.25-28).
So you had recognized your dangerous ambition. Then why commence?
Thou art mistaken, fool! You are wrong with your predicament!
Would you require another example?
Ah, this is yet another example of your ambition having dangerous control over you!
Your destructive ambition has caused you to wear a fruitless crown upon which only death can grow.
Aye, 'twas I who spoke hose words. But it means nothing! I'm not scared of you, you apparition.
Lie? Was it not you that said that "they placed a fruitless crown [upon my head]/And put a barren scepter in my grip / Thence to be wretched with an unlineal hand/No son of mine succeeding?" (3.1.61-64)?
