What a worthless, burnt-out coward I’d be called
if I would submit to you and all your orders,
whatever you blurt out. Fling them at others,
don’t give me commands!

– Homer

The Iliad, Book 1, lines 342-346. Having no respect for Agamemnon as a leader, the heroic Achilles is not afraid and has the courage of his convictions to stand up to the king. He tells Agamemnon that he will not submit to him and his orders, as to do so he would be called a worthless coward.
