Food for thought. The apostle appointed to Gentiles once went door to door rounding up believers and getting them condemned as criminals. Paul.

The thief on the cross was told he would be in heaven that day with Jesus after he expressed his faith.

David had someone murdered by the enemy so he could have his wife ... Yet he was ultimately forgiven and known as a man after God's own heart.

"For ALL have sinned and fallen short of the glory of God." (Romans 3:23) He is a perfectly JUST God, which means any sin must be atoned for. His standards are perfection, so no human could possibly live up to his standard and all would be doomed to hell. That is why his own son, God in human flesh, came to pay the price. But, as God respects our free will he doesn't force the gift on anyone. If someone doesn't wish to be with him for eternity, then he honors their desire and they go to a place of eternal separation from him.
