In the Act 1, the soldier and Duncan had described Macbeth
as great and brave man, which was pretty different to his persona in the Act 4,
where he was planning to revenge against King Claudius and the king’s family. He
remains a brave, however, in the last scene he was a bit spiteful and
vindictive as he was plotting revenge against the King Claudius, whom who have
killed his father.
