That Achilles is justified in his wrath against Agamemnon and his subsequent withdrawal from battle?

Achilles is justified in his wrath against Agamemnon because Agamemnon dishonors him by seizing Briseis, Achilles' prized war prize, which undermines Achilles' honor and status as a warrior. This act is a personal affront that fuels Achilles' anger, as it not only disrespects his contributions to the Greek cause but also highlights the arbitrary power dynamics among the leaders. By withdrawing from battle, Achilles asserts his dignity and the value of personal honor, demonstrating that he will not tolerate disrespect from Agamemnon, regardless of their shared goal in the war.
