Absolutely mental. Stay Alive Till 75! The witnesses in my village all gathered at the top of the hill in the centre of town in the morning to wait for THE end. Everyone could see them. They tried to sneak down quietly when nothing happened. All that stockpiling, not having children selling homes etc. to make sure that they were prepared. There was a lot of bitterness after that and loads of folk left, unsurprisingly.
Then there was all the fuss surrounding 1999. Same deal, folk not having kids, folk selling their house, not pursuing kind of career to spend more time in the ministry. And then nothing happened again.
The "generation" teaching doesn't even make sense anymore but people continue to swallow it hook, line and sinker. Girls and women still don't pursue education or careers, most men stay in menial, low paid jobs, all men remain head of their households, women still have to stay in abusive marriages. You still can't marry out. The teachings get ever more crazy and insular. The GB has such a hold over people, it's terrifying. Their hotline to God is unquestionable and they are still the good and faithful servant class.
The whole "personal decision" thing is a bit of a red herring as well, tbh. Every single decision that you make will have to be justified to jehovah at armageddon and there is so little mercy in the faith that if He doesn't like your decisions you will die a horrible death, so fear usually makes folk toe the party line.
