Brief summary and commentary on the first three scenes in Act III of Macbeth.

The first scene starts with Banquo voicing his suspicions about Macbeth killing Duncan in order to become the King. He is aware that the witches had prophesized that his sons would become Kings. But he doesn't let this thought obsess him. He is capable of controlling his thoughts and checking his ambitions unlike Macbeth which sets the two apart. Macbeth enters with the others here. He announces that Banquo is to be the chief guest …

…but there's no turning back so all he can do is move on. And one could argue that the witches and Lady Macbeth are responsible for putting him in this fix. As we watch these scenes, we can feel that Macbeth is gradually moving towards his inevitable doom but there's nothing we can do about it except perhaps sympathize and this can, at times, be frustrating. [I don't think the commentary here is very good]
