"Teary....Why do you think it is so important that ANYONE should be honest to such a dishonest cult? People were obviously making the best of a bad situation."
We are not talking about being honest or dishonest with the organization, we are talking about being honest with YOURSELF and with your GOD, who you make your vows to. Ethics and honesty are a matter of personal principles and values. Being honest with the organization comes in third, but that still hinges on the first two (you can't really do any without doing them all).
If you cannot fulfill your vows, then don't make them in the first place. If you think that the organziation is a lying 'cult,' then don't dedicate or report any time (one who believes that but still takes part in the Witness preaching work is also not being honest with himself).
