Even if a Pope maliciously WANTS TO DESTROY THE CHURCH, there is no Catholic teaching that this deprives him of the Papacy.
Ok, so let's assume you're right. This means there is NEVER the possibility that a pope loses his office. Because if Francis doesn't lose it, then nobody ever will. He's that bad.
This brings up the question...
Why did St Bellarmine, Cajetan, John of St Thomas, Suarez, etc....the greatest theologians of the time in the post-Middle Ages....why did they spend so much time pondering the details of why/how a pope could/would lose his office?
Their original answers were
a) "It's the 'pious opinion' that God would never let a pope fall into heresy." --- Well, we know now that God WOULD ALLOW this.
b) But if he did, here's what might happen.
If you are correct, then answer (b) should have been "But if he did fall into heresy, he still retains his office, until God removes him by death." End of debate.
But it WASN'T the end of the debate. These theologians did NOT say that the pope would always retain his office.
Which means he CAN lose his office. Their debate was PRECISELY upon the question of "What happens if a heretic pope loses his office and how would the church/cardinals respond?"
These learned men were open to the idea/possibility. Not sure why you're not.
