They don't care
They enforce the rules without compassion, dogma without dignity and punish with glee - it keeps the others in line. They have total control without guideline or being accountable to anyone.
I've been with this lot for 35 years - 12 of them as an elder.
Rule number one - no-one cares. I'f you've attempted suicide they will publicy reprove you and tell you to go more on the work (big help), if you've been disfellowshipped then "its in Gods hands - but Jehovah won't show compassion because the one who committed suicide turned his/her back on Jehovah. Rule Number two - if you want to get on as an Elder- be seen as a hard line, law enforcer. Disfellowship someone senior (pref another Elder) and you are seen as theocratic, strong and righteous. Rule number three - As an Elder - if you show compassion, reason or care - then the other elders make your life a misery (I know thanks - its what happened to me)
In your congregation - How many depressed, mentally ill, suicidal people do the elders visit to try and offer practical help - answer? The majority cannot be bothered - but they will chase you up if your report is late
