For example, Jehovah instructs us to “stop keeping company” with unrepentant wrongdoers. Despite our pain of heart, we must avoid normal contact with a disfellowshipped family member
Here the WT equate unrepentant wrongdoers with disfellowshipped ones.
It's extremely common to find thoroughly repentant ones who are df'd as a punishment or because their wrongdoing was common knowledge.
WT cleverly redefine "unrepentant" to mean "declared unrepentant by the elders" and the flock dutifully nod along, adding further anguish to an already crushed spirit.
