There is an interpretation of
The Illiad consistent with this reading – Achilles is certainly not the hero and probably not even the protagonist even if the opening line is on his rage.
It's Hector.
Hector is the one fighting a losing battle against a demigod like Achilles to defense his homeland, his family, his wife, and his child. The scene of him removing his helmet because it scared his infant son and comforting him before turning around, putting it back on, and heading back out there is heartbreaking.
He's clearly the most respected figure in the war by both sides.
His death and the dishonor of his corpse is the real tragedy.
Homer (and seems Nolan picks up on this notion) tells us again and again war makes great men into terrible men or dead men. Achilles, Odysseus, Agamemnon, it brings out the worst in all of them, and gets most of them killed, and only really Odysseus gets to have a happy ending after 20 years of suffering.
Oppenheimer was built around the same themes.
But not Hector. War kills Hector.
