One of the key plot points of my novel (which I'm rewriting again - probably as a result of a personal issue I'll discuss some other time) is a higher up similar to Ray Franz is about to go public with some information, knowing this the top dog has him killed. My fictitious religion is similar to the WTBS, but not exactly. It has similar controls, and a history of false prophecy which it has survived, much like the Watchtower.
My question: what piece of information could provoke such a reaction? In looking at the WTBS as a model so to speak, they seem able to survive anything - failed dates for the end, the UN scandal, pedophiles, the generation change etc nothing seems to have much effect. Is there anything (not necessarily true in the case of the WTBS - use your imagination) that could scare them that much?
