Hector has killed his best friend, Patroclus.
Achilles killed Hector mainly to avenge the death of his friend, Patrokolos. Also, it made sense for him to kill Hector because they both were the best fighters on their respective sides. If Achilles killed Hector, he would gain a lot of honor.
Hector kills Patroclus in the Trojan War. Patroclus, a close companion of Achilles, puts on Achilles' armor and enters the battlefield, leading to his death at the hands of Hector.
Patroclus convinced Achilles to let him don Achilles' armor and lead the Myrmidons into combat. In his lust for combat, Patroclus pursued the Trojans all the way back to the gates of Troy, defying Achilles' order to break off combat once the ships were saved. Patroclus killed many Trojans and allies including the Lycian hero Sarpedon (a son of Zeus), and Cebriones (the chariot driver of Hector and illegitimate son of Priam). Patroclus was stunned by Apollo, wounded by Euphorbos, then finished off by Hector. After retrieving his body, which had been protected on the field by Menelaus and Ajax (Telamonian Aias), Achilles returned to battle and avenged his companion's death by killing Hector. Achilles then desecrated Hector's body by dragging it behind his chariot instead of allowing the Trojans to honorably dispose of it by burning it. Achilles' grief was great and for some time, he refused to dispose of Patroclus' body; but he was persuaded to do so by an apparition of Patroclus, who told Achilles he could not enter Hades without a proper cremation. Achilles cut a lock of his hair, and sacrificed horses, dogs, and twelve Trojan captives before placing Patroclus' body on the funeral pyre.
Patroclus is killed by Hector, the greatest of the Trojans.
Patroclus (in the Iliad) was killed by Hector - who had mistaken him for Achilles (Patroclus had borrowed Achilles' armour). So if the question is: 'Who did not kill Patroclus?' the answer is: everybody except Hector (Aeneas, Troilus, Sarpedon, Calchas, Hecuba .....).
