'Witnesses refuse to kill each other.'
Yes. But here's the thing. An unlikely scenario I know, but, what would happen if the Governing Body had new light
to say that in certain circumstances it was now allowed, as in ancient Israelite times, to kill fellow Witnesses?
(to say that in certain circumstances it was now allowed to have organ transplants).
Blind obedience is all that is necessary. People like yourself would have a hard time reconciling the new light but I knew some who would follow what the leaders said no matter what.
