She should have died hereafter;
There would have been a time for such a word.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Shakespeare is explaining that Macbeth is realizing that everything he did was useless because he had to kill his best friend to become king, and also he had Macbeth pushing him in a way that she though was right. But now lady Macbeth is dead he thinks there is nothing to live for because also outside “his” castle there is ten thousand men disguised as Birham wood led by Malcolm and Macduff.”Creeps in this petty pace from day to day” Here Shakespeare meant there is a predator after Macbeth that comes day after day with a petty pace, and also he made a personification of time being a predator coming after Macbeth . Also Shakespeare removes the iambic pentameter from Macbeth’s speech which describes his state of mind. Previously Shakespeare also let the reader (us) know in some form of way that Macbeth’s mind was already deteriorating, e.g. when Macbeth sow a dagger appear in front of him with blood on it indicating that he had to kill his best friend for power. Also when he killed his best friend and he was still in the room and knocks where heard at the door and he though he wished that does knocks would wake him up. Shakespeare is trying to make the reader (us) to imagine using figurative language how Macbeth mind is right now, he doesn’t feel in place without Lady Macbeth, he thinks that living makes no sense now and he is thinking about everything he did just to become king.
