Answer: Macbeth's tragic flaw is his ambition to become a king at all costs.
Step-by-step explanation:
Macbeth is one of Shakespeare's four great tragedies, a story about a man who, together with his wife, develops a plan to come to the throne.
Macbeth wants to get rid of anyone standing in his way. He first murders King Duncan, and, because of the witches' prophecy that Banquo's sons will come to the throne, issues an order that Banquo and his son must be killed, too. Banquo dies, but his son escapes.
What Macbeth did not have in mind while driven by his ambition is that he would be consumed with guilt. Macbeth's life turns into a nightmare, as he constantly fears that something bad is going to happen to him. As he states in Act II, Scene II, 'every noise appalls me [ Macbeth ].' He is also wondering whether all the water in the ocean would wash the blood from his hands.
Macbeth's tragic flaw is certainly his ambition as well as the refusal to face consequences of his actions, which ultimately leads to his death.
