I'm sorry but I cannot agree. I know people who will follow the WT into the fire without a second thought. I pray WT eases up on the control, especially when it comes to child abuse.
In exodus the pharaoh's heart was hardened, and it caused great suffering before the end and resulted in the freedom of the Hebrews, but the demise of the Egyptians. It did work. What you are suggesting may be similar, the only difference is that the ones we want to save are not the Hebrews temporarily in captivity, but they are so misled and controlled that they ARE the Egyptians!
In the end if there is a God these trapped people will not be judged, and are free by the blood of Christ. Lets rather hope WT can come to the light and lets not wish more pain on its members.
