From a kid I was taught everyone who is not a JW would die at armageddon, only JW's would be alive. Everybody who was killed at Armageddon would be gone forever, those who died prior would be resurrected for a 2nd chance since they didn't have an opportunity to read the WT or Awake and learn 'the truth'. But those alive while witnessing if they rejected the WT or Awake were rejecting God and should have clearly known that they were rejecting him.
As a teen, it bothered me that in field circus we were offering magazines that had nothing to do with God or the end, and if somebody rejects the offer for the Awake magazine talking about genital herpes or something, how were they to know they were rejecting God? So if the WT or Awake weren't about the last days, etc, I offered the "Will this World Survive" tract.
In my young adult years I rebelled a bit and got to know some worldly people and other Christian and was further bothered that many of them seemed to be better association then other JW's and couldn't understand what made the JW's better on a 'technicality' of having the truth when others were just as and many times even more sincere and moral.
All of those contributed to my learning TTATT.
