let me rephrase, Pope can not infallibly contradict anything that was true before and is true now. He can however change discipline. Pope is still subject to time and place, he is still mortal. Torture argument makes no sense therefore; there were numerous occasions pro-latin Orthodox/Eastern priests were tortured and martyred.
Filioque? This again… saying it without Filioque does not mean it is not true with it. If you say “Jesus is God” does that mean he isn’t human? If you said “Jesus became human” does that mean he isn’t God? Nope. You did not deny the other. This is just your presumption. Mathematically speaking, Filioque or Non-Filioque are both true. Denying Filioque would not be true. No Pope denied Filioque, some just did not want it in Creed yet.
Popes allowing Capital Punishment? Before Pope Francis, Capital Punishment was only allowed in circumstances where nothing else was possible- but those circumstances don’t exist nowadays in our age. Pope just forbid it because circumstances never apply anymore.
Let me strike back with one question; why does 5th Ecumenical Council, infallible Eastern Council guided by Holy Spirit state this: " We further declare that we hold fast to the decrees of the four Councils, and in every way follow the holy Fathers, Athanasius, Hilary, Basil, Gregory the Theologian, Gregory of Nyssa, Ambrose, Theophilus, John (Chrysostom) of Constantinople, Cyril, Augustine, Proclus, Leo and their writings on the true faith. "(emphasis added). But Orthodox theologians deny Augustine’s theology (for example original sin) as “being cause of almost every error of the West”. Do modern Orthodox scholars have more authority than 5th Ecumenical Council? Aren’t Ecumenical Councils highest ecclesial authority in Orthodoxy? Aren’t they highest form of collegiality? Was infallible council wrong?
And you can’t dodge this with discipline being the case. This is dogmatic, doctrinal and theological in nature. If you presume to deny Augustine you deny Orthodoxy. If you support Augustine you deny Orthodoxy. There is therefore contradiction and hence Orthodoxy is wrong about this matter.
