Regarding Roman Catholic view on "bad popes"

[BobRyan]

Hello,
I came across a wikipedia article about a book entitled "The Bad Popes" by someone named Chamberlain. I'm sure it's a huge derogatory slamfest on Catholics

NewAdvent is a Catholic Website - not a protestant anti-catholic, bashing website.

They use a term "wicked popes" that you might find instructive.

CATHOLIC ENCYCLOPEDIA: Pope Boniface VIII
"Few popes have aroused more diverse and contradictory appreciations. Protestant historians, generally, and even modern Catholic writers, wrote Cardinal Wiseman in 1844, class him among the wicked popes, as an ambitious, haughty, and unrelenting man, deceitful also and treacherous, his whole pontificate one record of evil."

if go to their website and type in the search term "wicked popes" you will see their list.
