God, being Justice itself, cannot send someone to hell because they didn't have access to sacraments through no fault of their own.
Absolutely disagree. There is no doctrine that says this, nor has any saint postulated this.
God DESIRES the salvation of all. And He does not cast pearls before swine. Those who reject the natural law by sin, damn themselves. God will not waste the OFFER of sacraments to those hardened in sin. To some sinful people, He offers religion, because only He can read hearts and He knows who will convert. But to the many sinful people, He does not offer sacraments because they are swine. God does not waste grace.
