This teaching is very morbid and repulsive. Like Redvip2000 said, JWs just think of the prize, screw everyone else since they gave out "the warning" and people didn't convert to their religion. I don't think they really put themselves in other peoples positions and realize there are other points of view than what theirs is and that's why many people don't follow them. This teaching was one of the things that got me questioning. At first I didn't really think of the everyone dying senario, just getting through and the after. It wasn't until I really thought about it that I started to see the bigger picture.
My mom (who's realized that I'm having some doubts and not really concerned with going to meetings or the field service) threatened me with death at Armageddon twice if I didn't follow the organization and get serious with it. What really hit me was the second time when she said that I wouldn't make it. She'd have to wipe the tears off her face and bury me, but then she said she wouldn't even be able to find me under the mass amount of corpses lying around. That made really pushed it on how repulsive they can get people to think that, even of their own sons and daughters!
I know of one elder who's told me twice that he wants to get Michael Jordan's or Kobe Bryant's mansion. He said he's praying to Jehovah to let him have that place and not to destroy it at Armageddon. The whole time I was thinking: what's wrong with this guy?? Doesn't he know what he's saying?? looking forward for someone to die so they could take their house is really messed up and sad.
