Yes, Popes ‘can’ depose bishops. I tremble to think of it happening. Please see: “History”. There are usually horrifyingly painful schisms after depositions. You think this is undermining pastoral care? What about an authoritarian pope (not the one the liberals think we have, but an ACTUAL authoritarian) who deposes bishops left and right.
