Answer: A. In Act I, they think he is brave and honorable; in Act V, they think he is an insane tyrant who must be defeated.
Explanation:
It is very easy for everyone around Macbeth to notice that his desire to become a king makes him go insane. At the beginning of the play, Macbeth shows great courage during the battle, and is praised for defeating the rebel forces and their leader Macdonwald.
However, Macbeth gradually becomes insane. Driven by his desire to become a king, he murders both king Duncan and Banquo, which not only ruins his reputation, but makes the soldiers turn their back on him. In<em> Act V</em>, when Malcolm and Macduff approach Macbeth's castle, many soldiers desert Macbeth. They have realized what he has done, and see no point in fighting on his side anymore.
