I speak on conflict management, bullying and sexual harassment and part of that work emphasize healing work and proper apologies. One the many steps in a redemptive recovery is the abuser admits they did harm and asks what they can do.
Update. I find it Interesting that this happened. Then people outside the church, people not in the tribe, reacted that he had not acted properly and he eventually did step down. Tribes that are toxic often can't see their bad behavior. I believe this group felt themselves so holy they were, in fact, experiencing what I call "group narcissism". You can read other posts I have on that phenomenon.
