The fact that Achilles does recognize his kinship with those he has killed is what raises the Iliad to the level of existential tragedy. This recognition of kinship by Achilles begins in Book XXII. Before he kills Lykaon, Achilles says, "Come friend, you too must die." Most commentators have seen this scene as a sublime moment in the poem in which Achilles asserts the inevitability of death and suggests a kinship between Lykaon, Patroklos, himself, and all the other warriors who have died or will die in battle. This recognition of death is similar to the recognition by Meursault, in The Stranger, that his execution, his death, is the bond that connects him to all humanity. Like Meursault, Achilles is an estranged person, and his acceptance of the inevitability of death is his ultimate assertion of a common bond with all humanity.
This notion of accepting death reaches its zenith when Achilles returns the body of Hektor to Priam. During the last few books of the Iliad, Achilles becomes more and more aware of his own impending death. Even as he rages against Hektor's corpse, he sees his own demise foreshadowed. At the funeral games he rejoins his fellow Achaians. And with Priam, he rejoins the circle of humanity.
That words such as alienation, existential, and tragedy can be used to describe the Iliad demonstrates the greatness of Homer's achievement. The ideas that underlie the Iliad are the ideas that underlie all great literature. Interestingly, the first great hero of Western Literature is also the first modern hero of Western Literature.
