not a teacher
That was too absurd, too fantastic, to try even in the face of death.
Is this saying "when someone is in the face of death, he or she usually doesn't try to deny his or her identity"?
No, it means that denying he was Booth, even to try and save his life, was ridiculous and unbelievable. They knew for certain he was Booth, and Booth was aware of that.
