Solution:
Macduff suspects Macbeth of murdering Duncan and the guards. Macbeth very reluctantly accompanied Macduff and Lennox when they came to wake the King early in the morning. Macbeth was behaving in a weird manner because of his guilt, remorse, and dread of the uproar that was about to occur when Macduff discovered the body. Macduff did not understand Macbeth's cold, stiff manner and curt replies at the time. He thought Macbeth was angry at being.
