A second glance at this matter JeffT; I think that it would be most telling to know or discover if any of the GB have themselves "woken up". Surely this event is likely in due course!
If one of them realizes they are harming people by their delusional demands and continue in office-- that would be corrupt. It would however take a steely conscience and strength of character to let the other members down in their exclusive club and admit that they have all been in error, because it would likely spell curtains for the whole Watchtower delusion. I say this because some of the others in the GB will not be far behind in his thinking and the resignation of two or more would be a membership disaster because the flock would also start to wake up or be given the confidence to declare their own disbelief.
My guess is that in the spirit of a kind of Watchtower Free Masonry, the governing body of Jehovah's Witnesses feel a divinely ordained and privileged duty to fulfil their ritual obligations to carry forward the honour of being at the helm of this business corporation. They do not think like their followers; they are concerned with the prestige which exists within the executive and with their financial clout as a major world class stocks investor. They 'appear' blind to the stupidity of the perpetual delay of Armageddon because the vital key to running a domesday cult is to engineer belief so as to always be able to press the unattainable reward forward into the future.
However to be awake to this travesty and continue as a GB member would be first degree corruption.
