I never felt guilty about leaving in terms of the doctrine. It became more and more clear the more I learned that I'd made the right choice. I did feel guilty because I had to hurt people I cared about in order to follow my conscience. I had to leave behind everyone I once knew and broke bread with.
What hurt the most, and this dawned on me as I was reading CoC the first time, was that sense that no one I knew would ever believe me if I told them any of what I learned. They could never imagine that the people they trusted most were capable of manipulating information and people's lives in a way that I can only describe as evil.
But it certainly can't be described in the terms from the old loaded language, as in "leaving the truth". The truth was never there in the first place, so the only thing left...was "leaving".
