The elders want only 'justice' and 'repentance', and they really don't count repentance as something between the individual and God alone. They must get involved, and when they do, all H*** breaks loose.
Excellent comments from "Elton John".
The elders are trained to seek "justice" -- meaning determining whether or not a person is viewed as worthy to remain in the congregation or not. There is little or no assistance in actually keeping the marriage partners together. I guess we must have "justice" first, and we'll just see how the cookie crumbles (or the marriage crumbles).
The elders are trained to seek "repentance" -- but how can they read a person's heart? A person could be pouring out their heart and telling all these intimate details, but then the elders can still decide that a person is not repentant based on what THEY see. It's not easy work, and really it's very doubtful that such judgment belongs to men to do.
Repentance between "God and the person alone"? That's a foreign concept to the JW's, even though it is found in their Bible. But the WT Society leadership teaches that the elders must impose themselves on all these situations no matter how fragile, and then as Rocketman said, all heck (I think you meant "heck"!) breaks loose.
It doesn't matter much to the WT Society though if the people's lives are forever altered. They were probably spiritually weak and weren't contributing that much to promoting the publishing society's doctrines anyhow.
