Moral language around deception depends on perspective as well as rules. A commander who wins through a ruse is likely to celebrate ingenuity and repeat the method. The defeated side is more likely to describe the same conduct as dishonorable, as the Persians might have characterized the Greek refusal to fight in open water at Salamis. The Persians still chose to enter the confined approach, so moral complaint does not erase the command decision that made the trap work.

Successful deception is often praised by the victor and condemned by the defeated, making later judgments about chivalry inseparable from perspective.
