I do not want to judge whether any church is a force for good or bad in the world (that would be off-topic), but a few thoughts:
In raw numbers, there are few philanthropists that rival the RCC. But the RCC is also one of the wealthiest organizations in the world when it comes to land ownership, sheer assets and contributions from the masses. So it does not take a lot for them to outcompete many smaller charities that dedicate a much larger share of their assets to a cause.
As @curious mentioned above, an overall judgment needs to take both the positives and the negatives into account. Any organization that is over a thousand years old is going to have a lot of skeletons in the closet, and some of those skeletons might be the very reason they have so much wealth to put to charitable causes today.
Finally, to me Benedict represents pretty much the hard core of the church. He pretty much embodied all the good and bad that the church stands for today. Anyone who strongly identifies with the late 20th / early 21st century RCC will have lots of admiration for the man, but at the same time, the values he stood for and the things he did are also one of the principal reasons why all the people that are leaving the church these days do so.
