Were the GB members victims, too?
They certainly were before they became GB members, when they were seduced or born into the organization. They may have, probably did, fall for the same spiel they themselves were writing.
But that doesn't matter. As they rise through the ranks, from publisher to MS, then to elder, then to overseer, and ultimately onto GB they accept increasing responsibility within the organization, and as GB members are the final authority within the organization. Victims or not, they have a duty to the other members of the organization. They must question every assumption they hold, every decision they make, because their words and decisions affect the bodies and souls of millions of other people who are trusting them to make the right moves and not mislead them. When they make a mistake they are obliged to rectify it, when they don't know the answer they must admit it. If they realize these obligations are beyond them, they should step down.
Yes, I think they probably are among the victims. But for people in positions of authority, that is no excuse!
Ray Franz did the honorable thing, telling the world what was happening, not playing "yes-man" to hold onto his status. May he rest in peace!
