Answer: Macbeth believes Banquo and his son represent a threat to the throne.
Explanation:
Shakespeare's play <em>Macbeth</em> is about a man who, obsessed with becoming a king, is ready to do anything to achieve his goal.
Having murdered King Duncan, Macbeth becomes a king. However, after hearing the prophecy of the Three Witches about Banquo's sons coming to the throne, he decides that Banquo and his son Fleance should be murdered. Macbeth also fears that Banquo will eventually become suspicious about the truth behind Duncan's murder. Macbeth's plan falls short, as Banquo is the only one who dies, while his son Fleance escapes.
