I too was at Bethel and sat at the governing body table every day with all of the old time GB members and their wife's. Knorr, F. Franz, R.Franz, Sidlig, Jarred, Schroder, etc etc.
They were generally pleasant but they are in an altered state of reality and are quite caught up in being who they are. I don't think they sit around looking for ways to trick JW or get money from them per say but I do believe they realize that they've screwed up royally in so many ways. They like to put it all down to being imperfect and one could forgive them for that. The unforgivable thins is the way they never admit outright that they were wrong and that Jehovah isn't telling them what to say and do.
It's my opinion that they feel that for the good of the greater number, they are justified in just about any action that covers their tracks in order to avoid stumbling those who they've influenced wrongly. Most of us would call it lying and or cowardice but they call it "spiritual warfare". They are expert at convincing themselves of any number of delusional ideas and that includes the delusion that it's a kindness to the rank and file JW's who aren't as strong as they think they are, to shield them from too much reality including the fact that they aren't any more enlightened that anyone else.
