They have no respect for disfellowshipped people, even after they die. They would rather forget such ones, because they are not supposed to get a resurrection.
What I wonder is, what happens if a disfellowshipped person is working toward reinstatement. They have been to most of the boasting sessions, and have already had one rejection toward a reinstatement hearing. But, this person gets in an accident (perhaps en route to the Kingdumb Hell) before getting another chance for another hearing, and obviously is still disfellowshipped. I wonder if that person will get a decent funeral, or if the Filthful and Disgraceful Slavebugger claims a resurrection hope in that circumstance.
