Arlene's personal statement is not much different in fantasy from your evangelistic atheism.
There are lots of people who recognize the power and presence of evil in ghis world. I've posted the link to The Screwtape Letters by CS Lewis--an interesting fantasy. Or, you can read The Book of Job in the Bible for other illustrations. Arlene gave us her own fantasy--real in its own way--and I found it delightful!
