Hopefully this helps you! Macbeth is an amazing play write so, I hope you enjoy it ^^
In Scene 3, lines 143-147;
Macbeth reveals that he does not want to through with the plans of killing the king because he is destined to become the king, there is no reason to risk the chance of not becoming king.
In act one, scene 3, Macbeth says [Aside] “My thought, whose murder yet is but fantastical, Shakes so my single state of man”. His ambition stirs to the point where he abandons the philosophy of morals. We are able to see through his character and understand what type of person he truly is. The audience is able to see that in reality Macbeth has low moral standards although he appears to others as a man with high moral standing.
