In this ideological frame of a completely surrendered, open minded sheeps the disfellowshipment (DF) has a perfect fitting role in the system of funcionalized obidience.
On one hand disfellowshipment is not really so much a chastidy method for healing a weak charakter than it is useful to control „the performing of the WT-functionalism“. It doesnt play so much role in reality what kind of character-problem one admits, how fast and if one repents at all internallly, but what counts is to show publicly that everything is okay, to perform activity. Not to perform in the boundaries of this system of WT-functionalism is seen as "disobidience".
On the other hand disfellowshipment is the ideal measure that makes the ideological system of trusting a „good associtation“ complete. In fact through the complete separation of the fellows from the disfellowshipped the impression appears for the sheep of being in a safe haven in the congregation, that the good assosiation is yet more clean, yet more trustworthy if its protected by the chastidy of disfellowshipmment. The fellows so close ranks and trust only the fellows who are good association.
An offender would try to function and to remain so in good standing. The victim would funtion and try to obey and hear to the elders and not be loud but silent, because disobidience is worse than a sin.
The offender has to play the innocent because he doesnt want to loose the only power he has namely observe the funtions of those who fear him, because he has no real friends, but only functions, he doesnt want to loose his authority and functions and tries to misuse them to protect the position if necessary. He wants to remain good association and spiritual leader for the other family-substitute friends.
The victim likewise wants to remain within the bounders of "good association" and keeps silent not to loose its good standing or because this would be against the order or could end in disfellowshipment.
