There is a lot to criticize in the media coverage.  But this could be the worst of it all:

Diane Sawyer asked New York’s Cardinal Dolan if the Pope’s declining health hadn’t been brought on by the “burden of what the Church has been through with the scandals.”

Sawyer speculates on a motive without any evidence of that motive. And all she's doing here is asking Dolan to speculate along with her, most likely. I mean, what are the chances Dolan would know that, even if it were true?
