If everyone fails a math-test, that doesn't mean the test "no longer exists within a right-wrong binary". It simply means that no right answers exist. Likewise, just because a story, in the event, is full of wicked people, doesn't mean we aren't applying a moral binary.
Alternatively, you can read the Aeneid, or Homer, or The Northman. As I have explained in detail before, it is not that these stories are truly "amoral", but the ethical systems they map on to are utterly alien from ours. They truly escape our binary.
