"O, never Shall sun that morrow see! Your face, my thane, is as a book where men May read strange matters. To beguile the time, Look like the time. Bear welcome in your eye, Your hand, your tongue. Look like th' innocent flower, But be the serpent under ’t. He that’s coming Must be provided for; and you shall put This night’s great business into my dispatch, Which shall to all our nights and days to come Give solely sovereign sway and masterdom."(1.5.67).
"If it were done when ’tis done, then ’twere well It were done quickly. If the assassination Could trammel up the consequence, and catch With his surcease success; that but this blow Might be the be-all and the end-all here,But here, upon this bank and shoal of time, We’d jump the life to come. But in these cases We still have judgment here, that we but teach Bloody instructions, which, being taught, return To plague th' inventor: this even-handed justice Commends the ingredients of our poisoned chalice..."(1.7.1)
"What beast was ’t, then, That made you break this enterprise to me? When you durst do it, then you were a man; And to be more than what you were, you would Be so much more the man. Nor time nor place Did then adhere, and yet you would make both. They have made themselves, and that their fitness now Does unmake you..."(1.7.52).
The quote from Lady Macbeth shows that she is very vicious and evil-minded as she thinks that killing King Duncan is the only way for Macbeth to seize the crown. In addition, she said that she would renounce her womanhood. This conveys that she would do everything she can for Macbeth to gain the crown. Lady Macbeth also mentioned that she will take charge of the plan to kill King Duncan. This establishes Lady Macbeth as the dominant partner in the relationship.
“Is this a dagger which I see before me, ... Or art thou but A dagger of the mind, a false creation, Proceeding from the heat-oppressèd brain? ... Thou marshall’st me the way that I was going, And such an instrument I was to use... I see thee still, And on thy blade and dudgeon gouts of blood, Which was not so before. There’s no such thing. It is the bloody business which informs Thus to mine eyes. Now o'er the one half-world Nature seems dead, and wicked dreams abuse The curtained sleep... Thy very stones prate of my whereabout, And take the present horror from the time, Which now suits with it. Whiles I threat, he lives. Words to the heat of deeds too cold breath gives.”(2.1.42)
The soliloquies from Macbeth explains that he was pondering the idea of killing Duncan but he fought against his ambition of seizing the crown and started having second thoughts about murdering a good King. He realises that King Duncan is his "kinsman", Macbeth is Duncan's subject so he has to show loyalty to the King instead of harming him. Moreover, the King is the guest of Macbeth who is the host, so he should be protecting the King. Finally, there is no reason to kill this generous and virtuous king. This shows that because Macbeth is kind, he decided not to kill Duncan because there is no reason to do so other than his own ambition to gain power, which would be unreasonable.
"Whence is that knocking? How is ’t with me when every noise appals me? What hands are here? Ha! They pluck out mine eyes. Will all great Neptune’s ocean wash this blood Clean from my hand? No, this my hand will rather The multitudinous seas incarnadine, Making the green one red."(2.2.69).
The quote from Lady Macbeth shows that she hates Macbeth's personality where he is all talk and no action. That is to say, she is outraged about the fact that Macbeth does not want to kill King Duncan. Thus, she tries to persuade Macbeth to carry out the regicide by insulting his masculinity because she knows that by belittling him, she will be able to get Macbeth to do anything that she believes needed to be done. And she tries to manipulate him by hinting that only through his murder of Duncan will he be considered a man to her. This shows that she would do everything she can to archive what she has sworn to do, in other words, she is selfish and gives little regard to the feelings of Macbeth.
"Wherefore did you so?"(2.3.115)
"Oh, yet I do repent me of my fury, That I did kill them."(2.3.113).
The soliloquies from Macbeth shows how he was so obsessed with the murder of King Duncan so that he starts hallucinating an imaginary dagger floating in front of him. The imaginary dagger helps depict a manifestation of Macbeth's thoughts and unease considering the regicide that he will soon be doing. This dagger's tip is pointing to King Duncan's room and he sees blood on the blade which conveys harmful and violent actions. This indicates his determination to conduct the regicide and that he is no longer pondering about whether to kill the king or not. The fact that the handle of the dagger is pointing towards Macbeth shows that he already decided to murder the King to seize the crown which is his ambition.
The quote from Macbeth shows his sense of guilt and regret after murdering Duncan. Even though at the beginning of the play, Macbeth was described as a strong, noble and brave general who is loyal to his king, he could not withstand the distress and misery when he killed Duncan and the sickly and horrible feeling of remorse have entered his mind. As a result, Duncan's blood is the symbol of Macbeth's guilt as he mentioned that there is enough blood on his hand to turn the entire sea red and it will stay with him until his death.
The quote from Macduff shows that he is an observant man because when Macbeth declares that in his rage he has killed the chamberlains, Macduff seems suspicious about the reason why Macbeth killed them. However, Lady Macbeth faints to head off further questioning. This shows that Macduff is very smart and that if Lady Macbeth had not fainted, Macduff may have been able to reveal that the real killer of Duncan was Macbeth.
