I can't see Lelouch doing that, somehow, because it'd be like shirking his 'punishment'. He's not the sort of person I don't think who would allow Suzaku to be punished but not himself, when he feels like he really deserves it.
Sure, he could be a cold, manipulative bastard at times, but it was all for the good of all.

...On the other hand, maybe he was intending to die. And C.C. was praying that the code would come through.
Hopefully.

Arghhhh...trying to convince myself to stop bawwing and that Lelouch is alive is very hard.
