Pope Paul VI, shocked, broken-hearted, depressed --- wrung his hands --- did nothing --- and, on meeting with his critic Cardinal Suenens, buried his face in his hands and said, "Yes, pray for me; because of my weaknesses, the Church is badly governed".
For whatever reason, Paul VI blocked good Bishops from bringing any corrective measures against the arrogant, defecting lower clergy, failed to support the faithful laity, failed to educate the huge mass of confused people in the middle. Gained the doctrine, lost the flock.
Interesting history. Even Popes are human. He wrote the right stuff and apparently was taken off guard by the closeness of his enemy.
