Betrayal is the greatest possible wrong that can be committed in the world of The Lion, the Witch, and the Wardrobe...and we're saying that in a world where people are turned into statues, sacrificed on rocks, and drafted into the army at a very young age.
The consequences of treachery are not limited to the information recounted by a spy or the tactical advantage he gives. Instead, traitors themselves are forfeit to the other side, and they can only be redeemed by the sacrifices of others.
