Great News Cognac!!!
I think this is one of the most horrific JW teachings but it's also only half-way admitted to in the publications on a regular basis. Like in this last Sunday's WT lesson. JWs are involved in a "life saving work". They don't complete the thought by saying that 6 billion will be slaughtered. I think that part makes it easier for a JW-loyal spouse to say "Well I don't think Jehovah will really do that."
Sounds like our spouses are on about the same page. I'd say my wife is currently 97% JW-loyal.
