"Both of you, know Banquo was your enemy!!" (3.1.124-125)
Macbeth in the End
"I conjure you, by that you profess (4.1.51)"
In the beginning, Macbeth was a generous and a loyal man. His encounter with the witches, however, started his inner conflict. In this scene, Macbeth is conflicted as to whether he should kill King Duncan or not. His hesitation shows his nature of consideration of others. Therefore, in the beginning, Macbeth is hesitant and care about the consequences to his actions.
The decision to send murderers after Banquo is Macbeth's shift. His suspicions of Banquo grow due to the prophecy of the witches for Banquo. His lack of hesitancy to murder his best friend shows the change in Macbeth's character. While he was hesitant to kill Duncan, he doesn't waver when making the decision to convince the murderers to kill Banquo. During this scene, Macbeth appears to be more blood thirsty and overly ambitious. This ambition causes him to act irrationally too.
Macbeth's character in the end is overly ambitious which will cost him his life and throne. In this scene, Macbeth visits the three witches and demands the witches his fate. As the witches tell him of his future, Macbeth grows frustrated and decides do irrational things. Clearly, Macbeth came to the witches, however, Macbeth completely ignores their warning. Therefore, by the end, Macbeth is willing to do anything to secure his throne and he is not listening to anyone.
