X-Men Movieverse Fan Fiction
Kurt and Bobby isn't a pairing I had considered, but I like the way the interaction is handled.
Your idea that the sins on Kurt's body aren't all his, but simply a listing of all possible sins is different and not the way I interpret it, but your concept is certainly valid and well presented. I like the way specific sins are named and identified by location. But it's even more perceptive to have him realize how the sins that truly may be his are in fact the ones that he has left off.
