Not all the Popes have been good people. It is okay to disagree with them.
Pope Stephen VI (896897), who had his predecessor Pope Formosus exhumed, tried, de-fingered, briefly reburied, and thrown in the Tiber.
Pope John XII (955964), who gave land to a mistress, murdered several people, and was killed by a man who caught him in bed with his wife.
Pope Benedict IX (10321044, 1045, 10471048), who “sold” the Papacy
Pope Boniface VIII (12941303), who is lampooned in Dante's Divine Comedy
Pope Urban VI (13781389), who complained that he did not hear enough screaming when Cardinals who had conspired against him were tortured.
Pope Alexander VI (14921503), a Borgia, who was guilty of nepotism and whose unattended corpse swelled until it could barely fit in a coffin.
Pope Leo X (15131521), a spendthrift member of the Medici family who once spent 1/7 of his predecessors’ reserves on a single ceremony
Pope Clement VII (15231534), also a Medici, whose power-politicking with France, Spain, and Germany got Rome sacked.
I hate it when that happens.
You can disagree with the pope on some matters. What you can’t do is ignore him on faith and morals.
The bad Popes strengthen my faith. They show that even if a pope’s personal life is reprehensible, the Lord still won’t allow him to formally teach an error in faith and morals. My faith is also strengthened by Pope Paul VI going against most of the world and probably a majority of Christendom with Humanae Vitae in 1968. Sadly, “a majority” of Christians is now most Christians.
