Not defending the guy or anything, but I wish he had at least lived to tell his story. In my opinion, he is the most fascinating Islamic extremist in the past decade, and this will only serve to add to his mystique.
I agree he is very interesting, but I can't imagine him caring enough to write about himself. Everything from his actions, to his morals, and military experience already speak loudly enough for him. It would be interesting to know if he's really did. And if he is, then what will happen moving forward.
