Macbeth is a brave and skilled warrior, but he is also weak-willed and easily manipulated. He is unable to resist the temptation of power, even though he knows that it will come at a great cost. He is also quick to anger, and he often acts without thinking. This impulsiveness leads to many of his mistakes.
Macbeth is a tragic figure because he is ultimately destroyed by his own flaws. He is a victim of his own ambition and his own inability to control his emotions. He is a cautionary tale about the dangers of unchecked ambition and the power of guilt.
