I can't find the exact quote (I'll keep looking) but Charles Swindoll said of church discipline "we're the only outfit I know of that shoots its own wounded."
I think that is a very apt way to say what JW's do. About twenty years ago a relative was diagnosed as bipolar. Her behavior was bizarre to say the least, she had a problem with sexual obsession among other things. She was advised to see a psychiatrist and take meds. The elders told her not to see the counselor and she hated the meds and stopped taking them. The elders, in their loving kindness, disfellowshipped her. She's been drinking herself to death ever since.
I know we all know a thousand other stories like that. How many people, hurting, crying out, seeking help (or needing it even if they don't know it) and get kicked in the teeth for having troubles?
