As always, impeccable work Paul. Refreshing to hear you are pursuing other interests and remarkable that you still found the time and desire to put together and share such informative personal examination of the topic and the perspective of Raymond.
Every JW suffers the same delusions as described vividly of the GB. While the GB are in the highest positions, the organization is designed to make everyone feel there is another rung of the ladder to be achieved. No one is ever doing enough. Always move forward, improve, "reach out". Knowing full well no extra days of everlasting life will come from it.
The higher the position, the greater burden in the mind when doubts creep in. "The harder they fall" as it were.
The GB are painfully ordinary men playing the only game they know at the highest level in full recognition, or at the very least cognitive dissonance, that everything they believe in is in fact complete bullshit.
Do doubt each one of them quietly struggles with their own crisis of conscience.
