***To keep the analogy complete, the Catholic view is that God creates His children and then stands by them.***
The Protestant view is that God created all things, and then chose some to add blessing to. Those he chose to recieve eternal life love him forever, those he did not choose, ignore him, run from him, hate him. All of this is found in the Bible.
In your case, if God creates and then stands by them, how do you explain the fact that some never know him, never worship him, some are indeed sent to hell? That would mean that God is not powerful enough to save his children, or that he doesn’t care enough to save them. Either way, it doesn’t appear to be the God of the Bible.
I don’t know who gets to experience everlasting hellfire, but all indications are that they are those who reach out for sin instead of God; they reject His Grace. We understand that God’s Grace is for all men. God knows that some will reject Him; He will gather the many; he does not reject any man any more than the father of the prodigal son rejected him. But just as the prodigal son was enabled to return to his father, all men are enabled to come to God.
As to the virtuous pagans, that is outside our knowledge. We are instructed to evangelize and bring the Word of God to all. But what will happen to them is up to God; we will be judged on how many we have or haven’t brought the Word of God to. How many did we feed or clothe or visit? How did we treat the lest of our brethren?
