You can't be serious.
"That man" refers to every person who causes scandal, which probably everyone is guilty for, at some point in their life. "That man" doesn't refer to 1 person. 
I hope some of you are trolling because otherwise, the general, Catholic IQ is much, much lower than I thought.
Well duh, obviously.
There are degrees of sin and degrees of culpability. There are also degrees of influence.
Every soul on the planet knew who Begoglio was, his every public utterance was conveyed around the world
by the media and on the internet. Not a week went by that he didn't use the enormous reach of the papacy to
create scandal for the specific purpose of undermining 2000 YEARS of Catholic tradition.
So, yeah...THAT MAN is MOST responsible for creating scandal these past 12 years and woe to him.
