No the JWS do not have hell and brimstone within their doctrines as other Christian based faiths do,
they use the great destruction of Armageddon which most of mankind will be destroyed, very soon as its lamented
continuously in their Literature articles and public talks.
Before go on lauding over how pure and righteous the JWS seem or appear to be.
I'd suggest you look deeply into the doctrines of this religion with a critical mindset.
As another poster mentioned this deadly doctrine of no Blood Transfusions has killed thousands of devout JWS including many children
who parents were JWS. This is real death not some fictitious ancient theology that may or not happen in the future.
You shouldn't make passing judgments based on some JW literature peddler knocking on your door with a smile on their face.
There is allot more behind that pretentious smile, that is being intensionally hidden away to be sure.
