To the OP
For people that are guided by conscience it is difficult, even more so if it's the jw style of minimalist self worth conscience. For people that can shut down their conscience it becomes easier in time. The analogy that Snare wrote is right on the money. I have over the years been involved in clandestine activities and know how to shut down the conscience to achieve an end. In fact some (worldly bikie and gang types) have said at times "Have you no conscience?" Once you master that aspect there is no danger to any perceived mental health as you see yourself as being on a 'mission' and nothing ,,, nothing else matters. A means to an end, I suppose. Suffice to say I am no longer involved in those activities. My mistake was returning to the religion, yes, to give it a second shot!! Huge mistake,,,, However, now, as a PIMO I'm on a 'mission' to release the friends I have made from the cult. So I'm using a past learned behaviour in this case. I think it's working as I'm using so much of the valuable information on this site and my own research and they are seeing the double speak but are heavily invested. Beautiful people trapped in a concept/cult.To answer OP question, you can fake it if there is an important reason,,,, and my firefox browser provides a brilliant distraction.
P.S. not a servant nor a microphone handler so there is nothing to lose, so to speak.
