I'm not saying those in power would even contemplate doing this, but I wonder just how far JWs would go to obey their leaders. Would they go as far as to kill, if they thought God had given that message to 'his people'?
It would probably take years of subtle changes in their message so that it didn't come as a big shock. It could be justified in a number of ways. God gave them this message, who are we to question God, it is God's test just before Armageddon, Abraham was tested too, even if we don't understand - God does, they will only be dying at Armageddon anyway, if anyone worthy of paradise is killed accidentally they will simply be resurrected, and so on.
HOW they manage to convince people isn't the issue here, I'm just interested in whether people here think JWs could actually kill for their religion. I honestly think they would. They have been brainwashed enough already to give up their lives and their children's lives if it meant taking blood. Those sitting on the fence would probably leave, but the rest could be turned into murderers if the WTBTS wished it.
Remember this isn't about what will happen. I don't think they'd ever do such a thing. More about what COULD happen if those in charge decided to set the plan in motion.
