All of the above - and it is by no means a complete list - were attacked/sacked/excommunicated while Ratzinger was head of the CDF or as Pope.
Where did this 'clean up' get Benedict and his smaller, purer Church? What did it achieve?
For NOT going down this route and behaving like a tinpot dictator, for attempting to 'convince' rather than bully, I give Francis an A+. (One of the above described Francis as "living amongst wolves." That should be taken into account while Fr Reese hands out the midterm grades.)
