Macbeth is a play full of darkness, evil, and tragedy. It is the story of a man who goes against his conscience and commits a horrible deed which leads to his destruction and loss of everything he has around him. This includes the relationship he has with his wife, Lady Macbeth. In the end, he can blame no one but himself.
At the beginning of the play, Macbeth and Lady Macbeth have a very strong relationship and this deteriorates later.
Act 1 Scene 5 is a key scene which shows just how close Macbeth and Lady Macbeth were at the beginning of the play; it shows their original relationship. Macbeth has written a letter to Lady Macbeth telling her of everything and in this letter states algo that she helped him to get everything for him. The following speech where Lady Macbeth doubts that he can get to the title of King "he is too full of the milk of human kindness" shows just how close they were. It establishes the fact that she knew him so well, she knew what he was like and it emphasises the closeness of their relationship. She speaks of how he has enough ambition but not enough courage. His "overiding ambition" is not enough. When Macbeth and Lady Macbeth speak, they speak to eachother with such closeness and bond; he calls her his "dearest chuck", his "partner of greatness". She knows that he is too weak to do anything and states her position in the murder "leave the rest to me".
In Act 1, Scene 7 establishes the force and power that Lady Macbeth posseses over her husband. Upon hearing of Macbeth's decision not to kill Duncan, she is outraged and starts to work her force and power upon him. She knows where he is most vulnerable and attacks him at his weak spot. She strikes him at his manhood and courage. This of course works on Macbeth and she knows that it will. No one calls Macbeth a coward. She says that he is a coward and attacks his manliness. "to be more than what you are, you would be so much more the man"....
