Achilles's reaction to Patroclus's death in the Iliad is one of intense grief and blind rage. Initially shocked and silent, Achilles processes his friend's death as the loss of a beloved companion and a personal insult by Hector. This grief transforms into a vengeful pursuit, leading Achilles to kill Hector and desecrate his body, showcasing his deep emotional turmoil and fury.

The three major consequences of Achilles's anger in the Iliad are: first, the Achaeans begin to lose the war as Achilles withdraws from battle, leading to many deaths; second, Patroclus dies while fighting in Achilles's stead, shifting Achilles's rage towards Hector; and third, Achilles's return to battle results in Hector's death, effectively ending the Trojan's hope of victory.

Achilles' rage at Agamemnon in the Iliad can be justified in the sense that Agamemnon was abusing his authority, trying to assert his superiority over warriors and heroes that would have been closer to peers than subjects. Therefore, Achilles appeals to Thetis, who appeals to Zeus, asking that Zeus support the Trojans against the Greeks, which would then vindicate Achilles and his grievance.

While Achilles' wrath is a central theme in The Iliad, the epic encompasses much more, including the interconnected actions and consequences of various Greek and Trojan characters. Achilles' anger at Agamemnon and its impact on the war is pivotal, but the narrative also explores themes of pride, heroism, and fate. The poem reflects on how individual decisions lead to broader events, making it a multifaceted story rather than solely focusing on Achilles' wrath.

Achilles's rage is the central driving force of the plot in The Iliad. His anger over Agamemnon's slight leads to his withdrawal from battle, which shifts the war's dynamics. This rage propels the narrative forward, influencing key events, including Patroclus's death and Achilles's eventual return to combat, culminating in his confrontation with Hector.

The rage of Achilles is a central theme in the Iliad. Homer begins the story by asking the muse to tell him the story--not of the Trojan War--but of Achilles' rage. Homer blames Achilles for the loss of countless Greek lives, and this blame is justified.

Achilles is faced with conflicting feelings of honour and patriotism as a result of his decision to withdraw from battle. He feels that he must either kill Agamemnon or sit by while others fight, but in the end, he compromises by allowing Patroclus to wear his armour into battle.

Although Achilles has a legitimate grievance, his pride prevents him from being satisfied. He expects to be able to dictate terms to Agamemnon.
