Eriil is a man who confides himself in the existence of the hunt. He values the ideology of purity in the Hunt. You hunt to keep yourself fed, you hunt to stay alive, and you hunt to thin your competition in survival. Though this is latent-ly evil in many aspects of his character, because he goes as far as claiming the ideal of being Apex Predator over those not cursed. 

Thus, Vera would want to "Smite" him if she ever found out he was a Lycan.
