In the face of Heresy there can only stand the pure, the Emperor's Chosen few. By the light of the Emperor's True Servants a Heretic can be redeemed, shown the error of his ways. The Traitor, however, can never be redeemed. He is forever lost to Mankind, and to the Emperor he is no longer His child. The Traitor must not be tolerated, he must be expunged and removed; his stain forever forgotten.
