8. Hershel Greene
Around the same time that Dale died, Rick's bunch picked up a new voice of reason in the form of Hershel Greene, a gentleman farmer and veterinarian who initially stubbornly resisted the reality of the zombie apocalypse. Once the truth of his and his daughter Maggie's situation sunk in, he became a wizened pragmatist, cutting through the emotions of any moment to find compromises and options that others couldn't see. His death at the hands of the Governor was one of the show's most tragic sequences; and the role he played in the overall dynamic of the group has never really been re-filled. P.S.: Your presence is much missed, Scott Wilson.
