Ray Franz cannot be held accountable for what the jackasses did when he woke up anymore than each of us can be held accountable for changes to individual elders, bodies of elders, family members, other JW's that have crossed our path before and/or after we wake up.
But putting aside "accountable" still causes us to have some things to think about. Did things change because of Ray leaving the G.B. ?
People are pretty sure the Governing Body was going to come down hard pretty soon on potential harm from former members. I doubt Ray sped it up too much. Perhaps he could have tempered the G.B. a bit if he remained as a member. But who can ask people to remain to aid others? Many of us would not do it, nor should we if that was/is our choice.
Ray was content to just leave, just like many of us have done. He would possibly have even kept going to the local Kingdom Hall for the rest of his life. But the G.B. put him in their sites and took their best shot. And Ray fired back with THE BOOK that has damaged the cult more than anything else so far.
So pardon me if I rank him up there with "hero" for his very normal human actions that led to such greatness.
