Macbeth is alone in one of the rooms in the castle and has second thoughts about killing King Duncan. He knows how powerful he could potentially be, but also knows the consequences of his actions if he is caught. Lady Macbeth comes in and basically tells him that his second thoughts are nonsense, and if she were him she would have done it. She feels strongly about the actions they are going to take and persuades her husband into doing the deed.
” LADY MACBETH
Was the hope drunk
Wherein you dressed yourself? Hath it slept since?
And wakes it now, to look so green and pale
At what it did so freely? From this time
Such I account thy love. Art thou afeard
To be the same in thine own act and valor
As thou art in desire? Wouldst thou have that
Which thou esteem’st the ornament of life,
And live a coward in thine own esteem,
Letting “I dare not” wait upon “I would, ”
Like the poor cat i’ th’ adage?
I dare do all that may become a man;
Who dares do more is none.
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. I have given suck, and know
How tender ’tis to love the babe that milks me.
I would, while it was smiling in my face,
Have plucked my nipple from his boneless gums
And dashed the brains out, had I so sworn as you
Have done to this. “
