What you are describing sounds very much like my ex brother in law. I could see him joyful that soon Jehovah will destroy all these wicked people at Armageddon. Every time there was some tragic news event on the evening news it was like he was taking delight in the fact that thousands of people might be dying but this is the signs of the last days. Just sick. Even as a dub this would turn me off.
I recall one of the last times I went to a convention, with my parents was shortly after 9/11. Some good elder friend of the family that we had known for years came over and talked to us. With the dubs the fact that I was not a good active dub was common knowledge so, he kinda mumbled something under his breath but loud enough for me to hear, "oh it is a wonder how some start coming back just because a couple planes flew into some buildings". You know that was my real wake up call as I don't think I went to too many more WT meetings or conventions after that.
