Good points Blondie and Room215.
One reason that many jws feel that way (or, actually, are conditioned to think that way) is so that when push comes to shove, they'll blame themselves when things go wrong, rather than blaming the "Organization".
What happens too is that this "Organization" becomes a kind of entity, but without a human face. The tendency is to idealize it, and also personalize it, and yet, because it is an organization and not thought of as a person or persons, it is seldom held accountable. Instead, people within it feel that only they themselves are accountable for failings.
This can be illustrated with what happened in 1995 when the "Generation" teaching changed. The organization said that "some of Jehovah's people" were given to speculation about dates, when in fact it was with the organization that speculation and the teachings it was based on originated. I recall vividly sitting there during that Watchtower study, trying to accept culpability for something that I, and anyone in that Kingdom Hall, had nothing to do with. Better that than blame the "Organization", I thought. But then I realized it was they that came up with such teachings not me.
