The pope was leading the Church. Your question is based upon false premises which is why you defend the schism.
No the Pope was engaging in errors and policies that were destroying huge parts of the Church and endangering millions of souls.
It is not a false premise. There are plenty of post conciliar quotes from the very people that were doing the damage, add that to the empirical evidence and the condition of the Church and "the smoke of Satan" was and is still billowing all over the place.
There was no schism. That was another bogus charge. Doesn't matter what a Pope says, error is error, lies are lies, injustice is injustice.
God have mercy on JPII and Paul VI for their participation in the attempted destruction of the Church.
