Wormtongue a cannibal?

[akhtene]

As for Saruman, I think his contempt for Gríma and his belief that this servant at least would always be loyal, if only through fear were so complete that the sudden attack came as a total surprise.

Could it be that Saruman, known for his great power over Men's minds, skilled in manipulating others, had lost all his sences and didn't see what Worm had been driven to? Well, I can't see it this way.

And yet another thought. I've read that it's believed by Christians that anyone who was murdered goes straight to heaven, no matter how and why it happened. This is used as one of the arguments for banning death penalty. If I'm mistaken here please don't take offence and correct me. But to me this explains the shadowy figure was looking to the west, perhaps believing that by his death he could get a pass home.
