Justmaybe (John, etc.)
I cannot imagine many rational men taking any other path!  And THAT explains why the rest of the papacy of Paul VI has pretty much been ignored.  The man clearly made a terrible mistake.  For that he could and WOULD have been forgiven, had he recognized his error, and corrected it.  When he did not, despite the blowback from not just the laity, but the clergy, then there was little reason (for me at least) to look beyond that one. 

I've no problem with people making mistakes: God only knows I've made more than my share.  What's important to me is that when we error, we recognize it, and correct it if at all possible.  When folks don't, THAT becomes a problem, especially when they subsequently try to play "high and mighty" with their positions, by telling others how they should act.

My problem with Michael's post is that it STARTS with the assumption that Paul was a great pope.  Paul COULD have been great, but he caved to Ottaviani, leaving the laity to hang.
