My husband and I studied with 100's of people during 21 years of pioneering, around 34 got baptized, some got disfellowshipped, some fell away and some are still in there. It has been very hard for me to accept that I was part and parcel of it all, the only thing I can say is that we pioneered in very poor areas, with high crime rates and therefore the people we "helped" did actually benefit in some ways. I did not like to control anyone, I just wanted to help people. We usually studied with single mums with lots of kids, drug users, mentally challenged people...you know how it is...people who are attracted to religion because they are vunerable in some way. I genuinely believed at the time we were helping them with a network (brotherhood), but after waking up and addressing my own doubts and problems in being a witness I am sad to think of those who are still in.
Interestingly some we studied with who live in another country heard we are not attending anymore, we received letters begging us to go back from them, it was strange to be on the other end after a lifetime of trying to help others become witnesses. Just another reason actually for the guilt and depression that I still fight today.
