Interesting theory; but I think you should swipe the Knorr/Franz duo.
I think Fred Franz was a true believer; delusional of course, maybe *the* most delusional of all, but that is the nature of a really true believer, after all. Everything in Franz's life and writings speak of that. Gee, he even stayed celibate for his whole life, like a medieval monk. When Knorr became President instead of him (although being older in age and in the 'truth'), Franz didn't care. Even when he did become President after Knorr's death, he wasn't a real leader; he was more like a symbol, or the Society's "wise man". The real power was the then-new GB committees.
On the other hand, Knorr was, and acted like, a business man. Remember all the business-like things he introduced: special training for house to house preaching, Gilead training, DFing and tightening of the membership rules (smoking, for instance), and a lot more. He was authoritarian just like Rutherford, and when the GB was established in 1971, it marked the decline of his power, which may have led to his quick decline of health after that, and his untimely death.
