Judas Iscariot was also chosen by Jesus as one of His Apostles. Did it mean all 11 others were bad?
The men you cited may have been human, made bad choices, but were Popes, Successors of Peter, in an unbroken line, nonetheless. When looking through your source, did you find anything you thought was good about any Popes? The first 16 were martyred for their Faith...
When looking through your catechism, did you find anything you thought was good about any Protestants??
(I've noticed you got half the number...)
