Answer 1

At the end of Act III of "Macbeth," Macbeth prepares for war primarily because **he believes the thanes are plotting to rebel against him**. His paranoia has increased due to the witches' prophecies and the growing suspicion that his rule is being challenged by those who are loyal to Malcolm and Macduff. This leads him to take preemptive action to secure his power.
