Is there nobody in a Flannery O'Connor story but the gargoyles?

In earlier posts I noted that, if you knew nothing about her, you'd be surprised to learn that Christian salvation is the "theme" of many Flannery O'Connor stories and (her 2) novels. In "Wise Blood," however, it's obvious that Christianity, redemption, sin, and, salvation is her theme -- all of the characters are imbued with a fervent religiosity. It's as if the world consists of nobody but sidewalk preachers and their prey. (Maybe in some parts of the South in the 40s that was so.) What's harder to get my mind around, though, is that O'Connor is a self-professed Christian. From the evidence here, it would seem that she could just as easily by an atheist and a cynic. Clearly, her main character, Hazel Motes, who spends his nights on the sidewalks preaching abut the Church Without Christ, is disturbed and reckless. We have no idea why he has taken on this mission, why he has set himself up against the world. Does O'Connor mock and hate him? He's a grotesque and an object of ridicule or bitter humor, O'Connor's and ours. If she can show that even he can be redeemed, then, yes, this is a novel of salvation and faith. But what about the world he is in? O'Connor seems to see all self-professed preachers and madmen (Enoch) or charlatans (Hawks and his lscivious daughter, Sabbath, and others). Are there no good people? Is there nobody in an O'Connor story but the Gargoyles? Herr vision is unique and wry and at times hugely entertaining, but it's a great challenge to read about these grotesques and to feel or believe that she has, or that her God has, any love for them.
