I would advise you to read the I.K.S. Gorkon novels and the forthcoming Klingon Empire: A Burning House by Keith R.A. DeCandido. Kurn/Rodek is a major character in those books, and the signs point to his memory returning in the next book.
I second this recommendation.

				
 sorry.  I mean, I understand  why Worf did what he did, but that doesn't change the fact that is wasn't very "Klingon" of him.  But to commit suicide wasn't the way of a warrior, and that would have condemned him to Klingon's version of Hell.
