Readable presentations on theodicy (problem of evil) theories? Are there any expositions of christian philosophical resolutions to the problem of evil that one can more easily follow, in any presentation (video / audio / book /coursera / whatever)? Being a progressive at heart, I tend to get turned off when a philosophical system seems to require unnecessary (and counter-productive) suffering, but still I would genuinely like to understand christian theodicy positions. As much as I like to ridicule the position that "evil exists because the evildoer along with the righteous must have free will", there is actually something beyond that.
The Doors of the Sea by David Bentley Hart, from an Orthodox perspective.

The Justification Of God by John Piper, from a Reformed perspective. This book is more focused on the question of how can God be called good if he has sovereignly ordained that some people be damned, but the existence of God is clearly an implication of that question. As it's written by a Reformed theologian you can't be quite sure that the answer isn't "because freedom!"
