This soliloquy from Lady Macbeth reveals her cunning and ambitious nature. She is willing to manipulate her husband in order to achieve her desired outcome of becoming queen. Lady Macbeth's willingness to go to extreme lengths to seize power establishes her as a dominant and morally ambiguous character.
Macbeth is seeing the ghost of Banquo and this is causing him to act crazily, spoiling the party. Lady M tries to get him to settle down. But things get worse. Macbeth starts to say things which might give away the fact that he had Banquo murdered. Lady M then decides that she has to get rid of the guests.
Lady Macbeth says king Duncan resembles her father, so she encourages macbeth to murder him.
The play doesn't say.
By Act 5 she has developed the habit of sleepwalking. She has also, unfortunately, developed the habit of sleeptalking. I say unfortunate because in her sleep she gives away her involvement in all of Macbeth's murders.
He is too full of the milk of human kindness to catch the nearest way.
In the original version of the play (Shakespeare's) Macbeth and Lady Macbeth do not have any children. You might of watched/read/heard a different version...
Just read that tonight w/ my kids - Act II, Scene II - Lady M's second line.
The day after he arrives at their home.
Lady Macbeth is the more forceful, probably because she is less foresighted. Macbeth knows the likely consequences of his acts, but she does not. She cannot imagine the downside to the murder; all she sees is herself as the chatelaine, hosting dinner parties. This lack of foresight gives her the strength to use everything she's got to persuade Macbeth to the murder.
"Yet do I fear thy nature; it is too full o' the milk of human kindness to catch the nearest way.""He that's coming must be provided for; and you shall put this night's great business into my dispatch.""We shall proceed no further in this business."
One example of diacope in Macbeth is when Lady Macbeth says "Out, damned spot! out, I say!" as she tries to wash the imaginary blood from her hands. This repetition of the word "out" highlights her desperation and guilt. Another example is in Macbeth's soliloquy where he says "utter confusion" in Act 5, Scene 5, emphasizing the chaos and disorder he feels.
Lady Macbeth advised Macbeth to ignore his conscience and continue with their plan to kill King Duncan, even if he could not say amen after his prayers. She believed that their ambition was more important than moral guilt.
