They seem to behave more like the Mob than a group of "loving concerned humble bible students just seeking to do the right thing" when threatened so... Do they actually need to kill someone when they have programmed them to "kill" themselves either literally through WT assisted no-blood suicide or WT assisted deep deression from being ostracized from the tribe and persecuted for telling the truth about it?
Either way a death of self occurs literally or figuratively. Becoming "apostate" is the struggle to regain the lost self.
Sorry I slipped into philosophy for a minnie there, back online now though lol.
