Sadly, I know of at least one person who committed suicide among JWs who left a note that said they felt that they could not attain paradise in God's New System any other way than dying before Armageddon.
When I was suicidal because of post partum depression many years ago, I had similar thoughts. This is really a very dangerous teaching in the hands of someone who is suicidally depressed.
Oh, an atheist friend of mine and I discussed this yesterday. She hates Christianity and Islam in particular because basically, almost all sects of it teaches that you can put more souls into God's grace, (either heaven or paradise, respective of what you believe God's ultimate reward is) by executing them in his name or at a certain time than by converting them!
I'm reminded that Spanish soldiers in the New World used to carry vials of holy water to "baptize" Native Americans before they killed them so they could attain heaven, and justified their deaths as Christian acts of mercy in that way. They thought they were saving their heathen souls.
