King Achilles didn't want to fight because of their argue of Agamemnon in Book 1 but his decisions is inappropriate for a king because a king must do his best to protect his people. Even if he had an argue with Agamemnon he must not forget the responsibilities of a king. Because of his actions/decisions he is a coward warrior for he don't want to fight just because of their quarrel of Agamemnon. He must take care of his actions and think first before he decide because he is a king who must protect and serve his people.
