"Macbeth does murder sleep"- the innocent sleep
What is it you say? The life?
Banquo is being ambitious here. Even though he has ambitious thoughts, he does not translate those thoughts into action.
Who could have restrained himself, who loved Duncan and had the courage to act on it?
Macbeth mentions that he cannot sleep after what he has done, and that voices come to him at night telling him not to sleep. He is evidently haunted by his guilty conscience.
‘tis not done. The attempt and not the deed”
Macbeth is acting he does not know the news, and not relate to it. He starts to fear if people beside him will discover the truth, showing he is start to regret about the murdering. Macbeth does not want to give bad impressions to them as a new "Thane of Cawdor".
Let’s away. Our tears are not yet brewed.
Macbeth regretted what had done to King Duncan. In order to not being notice he is the murder, he said this quote to show others his respect and love to King Duncan, even though he kill him.
Lady Macbeth is losing her control because before she was bold and eager to kill Duncan but now she is feeling guilty. Lady Macbeth start to worry about affecting Macbeth's reputation if the others know the truth of King Duncan's death.
King Duncan's two sons, Malcolm and Donalbain do not want other people see them crying. Thus, they think that crying in front of people make them even more upset. However, their action of leaving the place made Ross, one of the nobleman, curious, which leads to more investigate on them.
