Perhaps his success in battle has made Macbeth want to advance himself further.
After the battle Macbeth and Banquo meet the witches. They greet Macbeth with reverence and tell him that he is Thane of Glamis, will become Thane of Cawdor, and will become King.
"All hail Macbeth, hail to thee, Thane of Glamis".
"All hail Macbeth, hail to thee, Thane of Cawdor".
"All hail Macbeth, hail to thee, that shalt be King hereafter".
When Macbeth found out that he had become thane of Cawdor he immediately believed the witches and everything they said. Banquo seems unsure about what the witches tell Macbeth. "Things that do sound so fair". Banquo is more suspicious because the witches speak to him in more riddles.
"Lesser than Macbeth, but much greater".
"Not so happy, yet much happier".
It is possible that Macbeth believes the witches very easily because now he has been told he will be king. He chooses to believe their words because they are favourable to him. The witches have shown they can tell the future so he will want to live up to his potential and because he has a lot of ambition he will want to do this as quickly as he can. For now he decides to leave becoming King up to fate.
Macbeth's soliloquy in Act 1 Scene 3 conveys to the audience his inner thoughts and the turmoil and confusion he feels. .
"This supernatural soliciting.
Cannot be ill, cannot be good. If ill,.
Why hath it given me earnest of success,.
Commencing in a truth?".
Through the soliloquy Macbeth tries to reason out what the witches have told him. The image of "Make my seated heart knock at my ribs" portrays Macbeth's anxiety.
Later on in scene 3, Macbeth thinks about how he can become king. The first thought in his mind is murder. "My thought, whose murder yet is but fantastical." This shows signs of Macbeth's more evil side, because only he put the thought of murder into his head. He soon tells Banquo that he has passed that thought and will not do it.
