I liked the idea...as an idea, as a theoretical construct or as a dream. I don't know if I really, truly believed, though
Yes!
I think that this describes most JW's. It takes a hateful s.o.b. to believe in the most literal sense that real soon now that God is going to violently kill (or in the euphemistic phraseology of WTS publications, "destroy") everybody who isn't a JW.
I'm tempted to pretend that I never was a JW the next time they come to my door, and ask them directly -
"From what I know of your religion, your basic message is 'Join us or else God is going to kill you' - is that correct?" And watch them squirm.
Fundies don't like it when you ask them what their religion teaches will happen to you if you don't convert, they just want to sell you on things like Heaven or Paradise. The darker aspects of their Faithâ„¢ is embarrassing to them, and rightly so, and they'd rather not discuss it.
