In the same way that persons writhe and caterwaul toward the Catholic Church's claims of truth regarding faith and morals, the same must be acknowledged about persons' rejection of the very source of their being, God.
While God longs and searches down the road to spy for the first signs of returning prodigal sons and daughters, being made imago dei, our free will contains within it the power to utterly reject the grace and being of our source, God.
Any system of thought that posits a reduction of this anthropology begins to lean toward the heresy of Calvinism, classical Protestantism, with its extremely high theology and low anthropology.
Will all those whom Christ encounters - perhaps eternally - when "he descended to the dead" freely choose to accept the grace proffered them, finally? That is out of our hands to speculate about, in my opinion.
What is certain is that in the here and now, there is no lack of rejection, reviling of, and actively working against the truths taught by the Catholic Church, the guardian of divine revelation. Those who live blithely ignorant or in agreement with such efforts to negate and suppress Mother Church need a conscience transplant.
