besty:
very interesting post, love it.
regarding OP:
Most JW, at least officially, obey whatever GB tells them.
I think, the difference is, how they feel about it. Take for example disfellowshipping: Some are really genuinely sad, that a brother or sister was lost to Satan, they will not talk to them, but they feel awkward and sorry.
Others again thrive of the punishment given to sinners, they feed their self righteous attitude, it puts themselves in a better light by comparison.
Another question is, why do people join ? The message, which is made clear early to bible studies, that most people will get destroyed at big A. Its one thing to get deceived into believing a happy future in paradise, but to think also, most people deserve eternal death the same time, does this attract ceratin kind of people ? maybe to a point, since most converts are ususally of the lower social rank, they have an axe to grind with scoeity in general. There are of course many exceptions to this as well.
