"Catch the nearest way"
She plans to be quick in planning what to do. Her first thoughts and actions as soon as she reads the letter, affect Macbeth so deeply later on, his character totally changes. She drives MacBeth to be evil, Lady Macbeth wants to be sure that Macbeth will get to be king of Scotland. She looks for the quickest way to do this for Macbeth, so he can get the throne more sooner. She gets a letter from Macbeth saying that was predicted to eventually become king of Scotland. As soon as she read the words, she says,
"thou. shalt be. What thou art promised"
She promises herself that Macbeth will become king of Scotland. After Macbeth and lady Macbeth decide murder Duncan, Duncan arrives at Macbeth's house as a surprise. Lady Macbeth tells Macbeth to put:
" This nights great business into my dispatch"
She controls Macbeth and tells him what to do as if she is in charge of the operation even though she does not murder Duncan. Macbeth suffers from the tension and worries of the crime they will commit. Much later in the play after the murder Lady Macbeth tries to calm and ensure Macbeth by explaining that:
"Things without remedy. Should be without regard: What's done is done".
Lady Macbeth's relationship with the supernatural causes her to become very emotionally involved with Macbeth’s Problems and to become quite evil. At one point, Lady Macbeth demands the assistance of unearthly evil forces
"You murdering ministers”
“Come, thick night”
“the dunnest smoke of hell"
She wants the assistance of the evil. Lady Macbeth is becoming wicked, she uses this wickedness to drive Macbeth.
By the end of the Play (scenes act1 scenes 5) Lady Macbeth becomes Very mentally and emotionally ill, she starts to go crazy, the murder or Duncan and Banquo. Mainly Banquo. Makes her full with guilt, she cannot bear the real truth.
“I tell you yet again, Banquos buried; he cannot come out on’s grave”
Lady Macbeth eventually goes delirious, carrying a lit candle wherever she walked these actions are a pathetic attempt to get rid of the real, evil darkness. She looks to Lady Macduff with sympathy. She feels so sorry of what has happened She starts to show sympathy and regret that she had never felt or shown before, when she was evil and wicked. When she is crying with sorrow she says:
"The Thane of Fife had a wife. Where is she now? What, will these hands ne'er be clean?"
Meaning that she could not wipe the imaginary blood of her hands, she visualizes it on her hands, and it is a sign of her guilt and regret of what has happened. She can’t bear the truth.
The guilt and remorse is slowly killing her and this part where she is sleep walking is the last seen of her in the play, because she dies. She is helpless now, she has no strength and power left in her to drive Macbeth and have confidence in success, this is what is so different about act1, she speaks differently, her script is written differently, the range of events that have happened lead her into destruction. After she has lost confidence and no longer has control of Macbeth, this may lead to the death of Macbeth, because he is useless without her, the two together are powerful. She now has lost faith and any enthusiasm that she had before. The downfall of lady Macbeth is not something sudden that happens in the play, not something that has happened after a certain event, her downfall progresses as the play goes from start to end, after a range of events that have happened. The death of Banquo, was not intended by lady Macbeth, This is one event. The death of Lady Mac duff and so on… Lady Macbeth is not even clear in the head on act 5 scene 1, she is not actually sane as she was in act1 scene5. But Act 1 Scene 5 is the start of Lady Macbeth’s downfall, as this is what sets her off and causes the problems. So it can be seen that the witches were all the cause of terror and destruction, if it wasn’t for them none of this would probably not have happened.
