I find that the essay seems to be an example of intellectual dissonance, a rationalisation of the moral flaws of religion. Evil is seen as a necessary part, and submission to that evil a worthy sacrifice. An idea I find quite chilling.
What I saw was an excuse to maintain a belief by allowing others to have a dissonant belief, expecting same in return.
Rather than find a humanitarian reason for charity, or just for caring for other people.
