I don't think the actual leaders (those behind the GB yanking their chain) actually have "soul" in the way you mean. For the sake of $$$ they continue to murder in the name of their Blood doctrine, which they are only reversing out of slowly over the years to avoid Law Suits.
I think they are in the postion of having to bring on some New Lighr P.D.Q
2014 loometh, and 100years and two things have happened, i.e not much and sod all, is going to cause every J.W to question more, to doubt more, to feel the pain of Cognitive Dissonance more.
The generation thing as they have spun it is nicely open-ended, but 1914 is a house of cards once examined, they need to spin away from their rigid attachment to that year.
What they cannot do is simply hope it will sink and be forgotten, as Rutherford's 1925 was, they have crowed about their wonderful perspicacity in pointing to 1914 for too long.
What they need to do is change the significance of the year slightly, but still allow for the G.B to claim legitamacy because of it.
Politicians with doubtful pasts should watch and learn from what they do, they will re-write history, etymology, semantics, even the Bible if they need to, but they will manage to drop the corpse that hangs around their neck.
1914 will go down the drain.
