Regardless of one's views on why Benedict resigned, etc, etc, his resignation merely sped up the advent of Bergoglio's "papacy". It twas going to happen eventually..it was just a matter of time.
Since there is a finite number of days until the end of time, it is not a waste of time to try to prevent a disaster like this papacy. I.e., not every evil “is going to happen eventually.” If the advent of such an evil can be delayed, it just might be prevented entirely.
There is also only a finite number of days before Bergoglio’s death, and the same principle holds. Every day Benedict could have stayed in office would have been a day closer to Bergoglio’s death.
There is an ample supply of Cardinals who are capable of being just as putrid in the papacy as Bergoglio.
It is true that some future Pope must begin the process of repudiating the vandalism wrought by the worst Pope in history (prior to 2013), Paul VI, and the abominations of Bergoglio.
At least Benedict spared us eight years of Bergoglio. That’s something. And with Bergoglio as Pope from 2005 to the present, no Summorum Pontificum.
