There are many times in life when one has to "go through the motions" until one figures out what to do or until there is no other choice but to make a big change. Looking back it seems to me that many JW's are in that state. They are in agreement with enough of the teachings, or believe they should be in agreement with all of them and feel they are to blame because they aren't or their life is so intertwined with it that leaving is just not in the cards for them. Only when there is some crisis or when they are seriously wronged does the house of cards collapse and change is unavoidable. Ray Franz was ousted. I don't know if he continued in the preaching work after that, but if he did it was likely because it was a way of life for him and he still felt compelled to spread God's word. I don't know where he would direct those who showed intrest. Perhaps he would have just encouraged them to read their Bibles or studied it with them and left it in God's hands to take it from there.
For him to have been reinstated he'd have had to acknowledge some wrongdoing on his part and admit his actions were those of an Apostate. Because of his former position, they'd likely have required him to make some sort of public apology. (example) We had a Bethelite who was made by the GB or whomever, to fly to the west coast to apologize to our congregation for breaking off an engagement with one of the sisters there.
