Final answer:
After killing Hector, Achilles dragged his body behind his chariot to the Greek camp and refused to return it for burial, demonstrating great dishonor in Greek culture. Divine intervention ultimately led Achilles to return the body to the Trojans.
Step-by-step explanation:
After killing Hector, Achilles dragged Hector's body back to the Greek camp, behind his chariot, as an act of revenge and disrespect. Hector's body was mistreated by Achilles, who refused to return it to the Trojans for proper burial rites. This act of desecration was seen as a great dishonor in ancient Greek culture, where funeral rites were of immense importance. Eventually, after divine intervention and appeals from Hector's father, King Priam, Achilles relented and returned Hector's body to the Trojans for a proper burial.
