Most of my knowledge of the confession and JC stuff surrounded the fact that it was not confidential whatsoever. My most recent cong was known for being super loose with the lips and we all knew what people got in trouble for.
I think for some caught up in the org, it can be a release, but those smarter know it is just a man-made rule meant to police things. I know plenty of elders who were going to topless bars at lunchtime, and sleeping with their sister in laws, and nothing ever happened to them, they still gave talks, etc. So Holy Spirit, Moly Lirit!
