Pax, how do you reconcile that the Church could give an “illicit and immoral” mass with this condemnation from the Council of Trent: “ Canon 7. If anyone says that the ceremonies, vestments, and outward signs which the Catholic Church uses in the celebration of masses, are incentives to impiety rather than stimulants to piety, let him be anathema.“?
1. The new mass is illicit, immoral and very, very probably invalid. You didn't mention invalidity, so I wanted to make sure this isn't forgotten.
2. The "new mass" isn't a mass at all, so your canon doesn't apply. The new mass is a eucharistic memorial, a communion meal, a Holy Thursday remembrance. No where in the new mass is there an offering, an offeror, a victim or a sacrifice offered to God. So it's not a sacrifice, hence it's not a mass.
3. The Church did not "give" us this new mass, because it did not come from the Apostolic Powers of the pope. If you read Paul VI's constitution which created the novus ordo, he says that he is creating this rite by order of the Vatican 2 council. He never created it by order of his Apostolic authority, so it is not a Traditional rite.
4. Even if Paul VI did create this rite using his papal powers, he did not order anyone to use it, nor is there a penalty for not using it. All he did was create it. So, the Church did not "give" us a new rite, in a strict legal sense. The Church created a new rite, but the creation of something is different than the use of it. Creating the atomic bomb is not necessarily wrong, for this is just an advance of technology and a discovery of atomic power. But USING the atomic bomb is wrong, except for extreme circumstances (and that's even debatable).
5. Quo Primum is the law on the books, both legally and morally, for the Latin rite. There's nothing preventing a bad pope from passing illegal laws or immoral laws. It's the obligation of Catholics to know their faith and to pray for guidance when they are confused. God will guide those of good will, as He did when people created the Traditional movement and rejected the evils of the new liturgy. Quo Primum was printed in every missal for centuries, and for good reason. When the new mass came out, people knew it was not the "old mass". They knew it was wrong. They went along anyway. They were not forced (except by their bishops and priests), but such force didn't come from rome. They accepted the new liturgy because it was easier.
