I believe that they are in advanced states of self-delusion, and when faced with evidence that they are wrong, they believe that it will be explained away in time by Jehovah, so they just bury their doubts and press on.
There are probably some who are there just for the sense of power that they weild over so many lives. Those are the ones that care more about the survival of the corporation than the beliefes, and may actually move over time to push the JW's closer to the mainstream. Don't know that they will ever dump the DF thing though. It gives them more of what they want; power.
Do you think that these super jerks have perks that come with power, like groupies? lol
