Answer: A. At the beginning of the play, they thought Macbeth was brave and honorable, but now they think he is a bloodthirsty tyrant.
When the play begins, Macbeth is an honorable man, who has had great success in his career and is admired by everyone. The soldiers find him brave and honorable, and would be willing to fight for him. However, as the play progresses, Macbeth becomes increasingly dominated by his desire to be in power. Once he is king, he is willing to do anything in order to remain in power. The soldiers who once admired him, therefore, start to believe he is a bloodthirsty tyrant who is only concerned with his own personal success.
