Scott McCall.

We don't know what he was like between the fire and s1, but we do know he was his sister's beta, and for some reason the S.A Hunter woman thinks he knows many languages. We can safely deduce many of his s1 actions were motivated by grief, and wanting to get back at the bastard that killed his only living family member. Even learning it was his uncle Peter wouldn't help that, if it were me that would only make it worse. In addition to the fact that Peter had lost his mind and there was no way to know that he would ever actually stop, or be controllable again, especially as an alpha to Derek's beta.
