One of the things that bothered me as a JW growing up was the idea that there would be a second Armageddon. They don't phrase it that way, but what else could it be when you read stuff like this from the 3/15 WT.
"Obedient humans will gradually “be set free from enslavement to corruption.” If they remain faithful to Jehovah throughout the Millennium and during the final test that will come at the end of it, their names will be permanently written in “the scroll of life.” They will enter into “the glorious freedom of the children of God.”"
So how pissed would you be if you are a loyal JW who happens to make it through the first big A, only to be faced with billions of rotting corpses and no services like electricity and running water? Once those problems are fixed, you are blessed with 40 bible studies a week, teaching all of the resurrected folk about how wonderful Jah is, although he just got done slaughtering 7 billion people.
But just because you made it through the first time doesn't mean you are safe. As referenced above, the "final test" at the end of the 1000 years means a bunch of people aren't going to make the grade, and its once again time to kill them off. And the supposed "perfection" that will come to humankind wasn't much of a comfort, after all we know how Adam messed the bed when it came time to be tested.
So how many die at the final test? And how many have ever lived? Wiki cites a study saying 106 billion, so lets just make it easy and say 100 billion. So once all 100 billion get indoctrinated about Jah for 1,000 years, Satan is released and the "final test" begins. The WT doesn't say how many die, going to the "sands of the sea" reference for the second death. I recall one talk from about 15 years ago where the speaker said we shouldn't be surprised if 1/3rd don't make it past the final test. Whatever the number, its going to be high when you start with 100 billion humans.
Imagine...another 33 billion slaughtered on top of the 7 billion at the first Armageddon. A lot of killing for such a "loving" God. No wonder so many are starting to nibble and sip the emblems, just stay a faithful JW and you won't have to deal with all of this new world bullshit, waiting around for 1,000 years to pass and having to go through a second slaughter of humankind!
