Act 1: Scene 4 - 7

Scene 4:
It starts off at the palace where King Duncan gets a report on the execution of the Cawdor before Macbeth that he died nobly and confessed his crimes.  Macbeth and Banquo enters the palace with Ross and Angus where the king applaud them for there heroism in battle. Soon after, the king spoke his intentions to his son Malcolm and Macbeth declares his joy.  Macbeth now has to compete for the throne.

Scene 5:
In this scene, Lady Macbeth receives a letter from Macbeth saying that he has gain the title of cawdor and that he would be king according to the witch's prophecy.  Lady Macbeth feared that Macbeth won't be able to the necessary steps to become king.  So lady Macbeth decides to change her resolve and convince Macbeth to listen to her so he will become king.  When Macbeth arrives, lady Macbeth discussed with him the plans of assassinating the king.

Scene 6:
In this scene, King Duncan arrives in front of Macbeth's castle where lady Macbeth went to greet him.  Duncan praised the castle for its pleasant environment and thanks her when she greeted him.  Then he ask to go see Macbeth and lady Macbeth led the way.

Scene 7:
In this scene, it starts off with the servants preparing the meal for the evening feast.  During that time, Macbeth starting wondering if he should assassinate the king or not.  If he would risk the punishment he might get.  In the end he realized that he had no reason to kill him besides his own ambition.  Lady Macbeth finds Macbeth and tells him the king require his appearance.  At the moment Macbeth told lady Macbeth that he no longer have any intention of murdering the king.  Lady Macbeth starting giving him reasons and what would happen to his pride if he doesn't.  Macbeth then questioned if they were to fail and she replied that it won't happen since she's going to make the guards drunk.

My reaction for these scenes only appears in the modern film.  I was surprised by the tone of voice used by the actors.  When lady Macbeth was telling how much of a coward he would be if he didn't kill the king in an angry tone.  Macbeth also had slight anger to his voice when he told her that she would only have male children.

During these scenes, I wonder why lady Macbeth is so obsessed in getting the throne for Macbeth?  Does she have some sort of reason?
Another question is; What does she plan to do with the throne once Macbeth becomes king?

I predict that Macbeth will keep his words when he says he doesn't have any intention and won't be swayed by his wife.
