If you were willing to give you life by not taking blood at some point. or by going to dangerous assignments then the answer is yes. I was sold on the idea that Jah Jah would give me back life and I trusted the GB so yes I would have and I think most JW would do too.
As a matter of fact there was a point when I felt so guilty and so unable to followed the rules that I wish I had a chance to demostrate to Joroba that I would give my life for him.
ALL faithful JW are under mind control so all of them would listen and obey. In the nazi germany regular, normal people obeyed their leader. All it took was a good emotional speaker that would move them to action. Imagine if they were a part of a mind control cult? then they would have done even more.
Have you seen the milgram experiment? I think over 80% of regular people would follow orders from an authority figure. How about the ash experiment? we also tend to agree with the group even if we disagree with the answer.
Now put all these factors together..... Authority obedience, group conformity, charismatic attraction plus being under mind control..... There is your answer. Any person who believes in their blood doctrine has already drank the kool-aid. We at some point already said yes. Thankfully we woke up before we had to take our lives.
Now would the WT ask us to do so... Maybe not right now but I dont discard the possiblity that in the future they would get new light to speed up the Armageddon or to reduce suffering or to avoid failing to Satan.
Thats the reality we like it or not.
