SBMFF
IMO he's not going to contemplate his actions for even 1 minute. Not even "where did I go wrong and get caught?". I'll bet in his head he does NO wrong and makes NO mistakes. He's perfect and smarter than everyone else.
What I believe he'll do is relive how it went down over and over in a perverted way. It's just about all he's got left. And I'm not one to advocate for lobotomies... but I'd love to rip that experience right out of his head. It actually makes me angry that he still has it and that no one can take that from him.
