That's the real kicker with JWs many that get disfellowshiped for some "offense" they admit to committing would say that it's painful and they don't like it's, but, they deserve to suffer the consequences because Jehovah's org has to be kept clean etc, and, if the situation was reversed they themselves would comply with shunning another.
I know, cause I've met them and I used to think the same way.
That's the chilling beauty of effective indoctrination, break someone's natural conscience to the point that they believe they actually deserve whatever punishment or emotional abuse is dished out to them, and that they have the right to enforce these "god-given" standards on others if ordered to.
Kind of sado-masochistic when you think about it.
