Should it be enough to apologize and move on? I would say that such apology is empty. There should be that part where people who were affected are made even as much as possible, where we reflect on what was supposed to be done differently and make changes for future.
There was really no one who voiced disagreement at the time? If no, why? If yes, what did happened to their career and status in the organization? How were they argued again, how did the fight at the time went? Were they retaliated against at the time?
All these things matter and should matter, so that next time people voice dissenting opinions in case like this and are listened to.
The difference is between "wanting blood" and "restorative justice." In former, vengeance is a motivating force, potentially with little regard to making amends. Simply inflicting pain can be sufficient. In other, the goal is to compensate, restore and reform. This may or may not require inflicting great pain or ruining someone.
