The really sad part is that he must have realized in his last moments how wrong he had been all his life. That everything he believed was completely backward. As he was being tortured, he had to think of what he was accusing the Americans of wasn't really torture at all. What he was experiencing from these terrorist was what REAL torture was all about.
Sadly, it was too late for him do anything, and there was no way to tell anyone, to warn them.
May God rest his tortured soul.
