<<Catholics: Do you think that God influences the Cardinals when they select a new Pope?>>
Absolutely yes. The selection of a Pope is an Infallible decision of the College of Cardinals. The infallibility of such a decision would be impossible if not for the guidance of the Holy Spirit.
<<Someone suggested that might be the case in another post. If that's the case, why do you think God selected so many bad Popes?>>
Bad popes such as? You have to give examples because there are plenty of misguided who think the likes of Pope John Paul II and Pope Benedict XVI were/are bad popes - but they are not, if I may say so.
<<(This isn't a slam against Catholicism, it's a question I've posed to my father, who says that there haven't been any bad Popes. I disagree--there have been Popes that have seriously harmed Catholicism and Popes who didn't live lives appropriate for that of a priest. Seems to me that it's an odd thing for God to do.)>>
You will get nowhere discussing ANYTHING pertaining to religion unless you - out of respect for your father - sugarcoat your potentially and legitimately offensive comments.
Clearly some popes have been better than others. Some have done great things for the Church, while others have indeed harmed the Church. Still, to refer to any pope as "bad" - meaning "evil" - that is, by all accounts - an extremist view.
<<By the way, I'm not Catholic, nor am I a believer, but I'm not asking this question to debunk, I'm really curious. So I hope you won't get angry about this question.>>
Many non-Catholics think, wrongly, that Papal Infallibility refers to every little a pope says or does the entire time they are the pope. This is incorrect.
Only when the Pope is speaking "Ex cathedra", that is - from the chair (of Saint Peter) - on matters concerning Faith and Morals, are the pope's teachings treated as infallible.
This isn't something that happens that often. If a pope were about to pronounce something "ex cathedra", you'd know. There would be no mistaking an infallible teaching for a "regular" teaching.
