Comment: 1. I am not sure what you mean here. What holds the bishops' attention, the ritual humiliation? There are many ways the bishops and clergy can cause scandal to the body of the Church. They can, e.g. indulge in non-criminal sexual impropriety, theft, etc, are they as a body to have to face ritual discipline on a number of issues?
2. I am sorry but I disagree with you on the principle of "corporate judgement for corporate sin". On the Last Day each individual, in this case each individual bishop will be called to account for his deeds before Christ; the College of Bishops will not be judged corporately. For this reason I don't think that "corporate sin" exists at all. Each of us has the choice of collaborating with others in doing evil or of not collaborating. Whether we join with them or not is entirely an individual decision as we are in possession of free will. I don't believe that there such a thing as corporate will.
That is the main basis of my thinking.
