I know Jehovahs Witness doctrine very well, having studied with them for over a year after a surprise visit. First thing I had learned about was there belief that there was no place of Everlasting torture. Spending time studying with the Witnesses, I had learned that they take their understanding of the New World Translation very seriously. I honestly dont know how accurate of a translation their bible is. But, Im well aware of the fact that their religion is very conservative, and do not drop biblical doctrines, no matter how unpopular they are. However, they do not except the idea of a burning hell, and I believe that if they did believe that the bible taught everlasting torture, they would not drop the doctrine like cold turkey, despite the fact that it is probably the most hated doctrine in Christianity.
JW's unpopular beliefs.
-No Holidays
-No Blood Transfusions
-No Homosexual behaviors
-Keep out of Politics
-Belief that all other religions are Satanic
-Belief in upcoming future traumatic disasters
+ no smoking
+ no sex before marriage
it is not actually a proof that there is no hell, but it is very much true that a conservative and sincere belief in no way demands the idea of a hell
