In Act III Scene II of Macbeth, a servant enters the scene escorting Lady Macbeth. She informs him to tell the king she wishes to speak with him.
Say to the king I would attend his leisure For a few words.
For the first time, Lady Macbeth feels guilty for her act of treason. She envies her victim because he is no longer able to experience emotions like anxiety, such as Lady Macbeth does.
...Naught's had, all's spent, Where our desire is got without content. 'Tis safer to be that which we destroy Than by destruction dwell in doubtful joy.
...Better be with the dead, Whom we, to gain our peace, have sent to peace, than on the torture of the mind to lie in restless ecstacy.
Macbeth enters the room with a very troubled conscience. Just as his wife, he too feels remorse for his crime. He is tormented with worry of the truth being surfaced.
So shall I, love, And so, I pray, be you. Let your remembrance Apply to Banquo; present him eminence... And make our faces vizards to our hearts, Disguising what they are.
Lady Macbeth consoles her husband whilst reminding him of tonight's guests. Macbeth Advises his wife to make Banquo feel important. He reminds her to mask her true ill intent.
Come on, gentle my lord... Be bright and jovial Among our guests tonight.
There's comfort yet; they are assailable... Hath rung night's yawning peal, there shall be done a deed of dreadful note.
Lady Macbeth hints that Banquo and Fleance cannot live forever. Macbeth is comforted by this thought. He tells his wife that Banquo and his son will be no longer before nightfall.
But in them nature's copy's not eteme.
Be innocent of the knowledge, dearest chuck, Till thou applaud the deed... And with thy bloody and invisible hand Cancel and tear to peices that great bond Which keeps me pale.
Macbeth says to his wife that it is better if she does not know his plan until it is done. He is certain that killing Banquo will help ease his worrisome mind. He then exits the scene with Lady macbeth.
