What kind of leader does Duncan appear to be in Macbeth?

In Macbeth, Duncan appears to be a just and
fair leader who values loyalty and honor. When the Captain returns from battle and gives Duncan
his report, Duncan is happy to hear that Macbeth fought so valiantly for Scotland. As a result,
Duncan rewards Macbeth's loyalty and bravery by naming him the next Thane of Cawdor. When Duncan
is murdered, all the Thanes vow to find his killer and to bring justice to the evil-doer. In this
way, the Thanes show that their love and loyalty to Duncan who was a good king. Finally, near the
end of the play, Macbeth realizes that he is without the love and loyalty of friends and he
thinks back to Duncan's time when he was loved by all in Scotland. These situations all suggest
that Duncan was a good and honorable king and leader.
