I'm 100% convinced that DC's writing staff is almost entirely comprised of evil conversion fetishists. It's a theme they've revisited over and over again, from FINAL CRISIS to BLACKEST NIGHT to DARK NIGHTS: METAL. They just can't stop flogging that evil horse.

It's not like my inner fetishist is complaining (well...sort of), but considering these kind of stories are usually written with little regard to the lasting impact and trauma an evil metamorphosis would have on a character, the other side of me that's more into well-told narratives isn't particularly excited.
