Gregory tops my list as the bottom of the barrel. I've always felt that the human villains on this show were more threatening and more horrifying than any of the proper creatures of the night, and Gregory possesses the worst qualities of any character that I've seen on this show.
While Rev. Trask I (perhaps he, like Sheriff Davenport, had parents with no creativity in the name department but plenty of plans for their son's future career) was cold and hypocritical, not above manipulating justice to get his way, he did believe that he was serving the will of God. Lamar, I suppose, had a reason to feel bitter (after his father's strange disappearance) and to act the way that he did. Personally I liked him more and felt that he was a better character when he was merely a self-righteous undertaker than when he fell into the familiar witch-hunter pattern. However, Gregory was motivated solely by his own greed. Murder, attempted murder, child abuse, and who knows what else--his crimes were committed without remorse. As a reverend, he was supposed to be a man of goodness, but subverted his position in the worst ways. Moreover, he just plain gave me the creeps in his looks and attitude.
