Yes, Roncalli set up the stage, and the spark was ignited by Montini. Luciani barely got a chance if at all. Wojtyla solidified and spread it. Ratzinger slowed it down and deceived. Bergoglio sped up the train aggressively. Prevost keeps it going even faster more covertly.
You'll notice how cleverly they worked this.
Wojtyla actually held the line on Catholic moral theology ... did nothing about it, of course, but at least paid lip service to it. Between that and his occasionally being seen within 50 yards of a statue of Our Lady with his eyes closed and head bowed, sometimes holding a Rosary, they managed to get everyone to believe that he was this "santo subito", a great saint.
Now, while people considered him a saint and he has this huge following among Conciliar conservatives, there was never a greater purveyor of religious indifferentism ever to (physically) sit in the Chair of Peter, where his activities along those lines make those of Bergoglio look like childsplay.
So Wojtyla gutted dogmatic theology, promoting religious indifferentism, and got a lot of Conciliar conservatives to swallow those heresies. If you listen today to the conservative Conciliar types, Catholic Answers, EWTN, you might think you're listening to some pre-Vatican II Thomists ... until they start talking about "separated brethren", salvation outside the Church, that the Sacraments are merely "helps" to salvation, etc. ... the wheels fall off into abject heresy. That's due to the Saint Wojtyla the Great psy-op that they bought and swallowed.
Once Wojtyla had finished the job there, they took a detour with Ratzinger to neutralize the growing Traditional movements, the opposition. Ratzinger failed ... thanks to Bishop Williamson, and that having been his ONE JOB, he was told to step down by their handlers.
Now comes Bergoglio to attack moral theology (which Wojtyla had left intact).
This is all a plan, designed by Satan, to take down as many as possible ... and it's really been rather brilliant.
