This article is fascinating in its choice of headlines. It briefly mentions the headline quote, and then goes on to primarily talk about the number of journalists who were killed last year. It was just an article about a conference the pope spoke at, but i really thought it'd be about something else before i read it. Successful clickbait, i guess???
Your first mistake is writing THIS POPE, when it should've been THE POPE. That will get more people interested, because it's THE pope and not just any regular pope.
I wonder if there are a number of people who will always read an article if the pope is mentioned, so if he's related to a topic even a little bit, he gets to be in the headline.
This is pretty off topic, but in traditional newspaperology headlines the story writers have no say in the headline. Headline writing is a separate discipline with specialized headline writers, because you have to carefully count the character sizes to fit the headline into the space.
This traditional art changed on its head when headlines online were no longer constrained by the page layout.
