This WTBS teaching destroys lifes and mental health.
Also they have many times "marked" individuals in the congregation as people to keep a little distance from. Not shunned, not DFed not DAed , but 'marked'.
How in the bloody hell is a Jw to trust ANYONE? Even themselves if the person they were just talking to at the meeting is 'marked' usually heard or overheard of ,after you spoke with said 'marked' person. Then one starts to feel spiritually dirty. Possibly and often questioning there ability to walk a spiritual path approved by jeho. Then its back to study study study . Dont think, just study. Even within the cong there is major mistrust and fear.
So outside the org must be millions of times worse by jws logic.
A recipe for a psychotic break. The GB rely on this fear. It must be forever present...always.
