Shortly before I left JWs I used to converse quite freely with a handful of close friends. One of them was asking me a lot of questions -- admitting there might be different answers than the JW ones, but stil clinging to the JW kind of questions which in her mind had to be answered one way or another.
One day I suddenly told her (I still remember the place, we were crossing a street in Paris): Perhaps we are not supposed to have an opinion on everything.
That was a very simple, even trivial sentence, but to a JW (and to me in that moment) it was a mind-blowing and liberating revelation.
This is particularly true, I think, in the "moral" sphere. We are not supposed to either approve or disapprove of every single action in the world, sorting it as "good" or "bad" or "indifferent".
Everything happens -- the "good" and the "bad," the "beautiful" and the "ugly". Moreover, everything is related -- we wouldn't have one without the others.
If we were REALLY in someone else's shoes it is very likely that we would be doing just what s/he is doing -- no matter how admirative or disgusted we may be from another (and often remote) perspective.
Over the years I found myself doing a lot of things which I would previously have looked down on or looked up to -- in both cases, that I wouldn't have understood.
I think the beginning of "personal integrity" paradoxically lies in "do not judge" (or, as the NWT more realistically and perhaps, for once, more accurately puts it, "stop judging"). Which is the very opposite of moral theory and casuistics.
