I did not mean those who will be part of the great crowd. That's obvious. They will never disappear. I meant those outside all of that and may be part of the Great crowd in the future. People who have a good heart who can be saved. When Jesus comes, he will make a separation and by that time, the difference between good people and the wicked ones will be absolutely clear. There will be no doubt. Currently, there are still good people outside of all that. Do you understand what I'm trying to say? People who have a good heart and do not harm others that can be saved but are not in the righteous path yet.
This part of this watchtower's article explains what I tried to say in some way.
"A Measure of Error to Be Filled
Studying God’s past dealings with mankind, we note that he often withheld his judgment until all hope of improvement was gone. In connection with God’s judgment upon the Canaanites, for instance, he pointed out their sins to Abraham long in advance. But the time for the execution of his judgment was not then due. Why not? The Bible says: “Because the error of the Amorites [Canaanites] has not yet come to completion,” or as the
Knox version puts it: “The wickedness of the Amorrhites [had] not reached its full term.”—
Genesis 15:16.

About 400 years later, however, God’s judgment came, and Abraham’s descendants, the Israelites, took over the land. A few of the Canaanites, like Rahab and the Gibeonites, were saved because of their attitude and actions, but for the most part, they had reached an extreme level of uncleanness, as is revealed by modern archaeological excavations. They practiced phallic worship, temple prostitution, and child sacrifice.
Halley’s Bible Handbook states: “Archaeologists who dig in the ruins of Canaanite cities wonder that God did not destroy them sooner than he did.” In the end, the Canaanites’ ‘measure of sin was full’; their wickedness had “reached its full term.” No one could rightfully accuse God of being unjust when he let the land be cleansed while sparing those who had shown a right attitude.
We find a similar picture in Noah’s day. Despite the fact that people before the Flood were wicked, God mercifully decided that their time would continue another 120 years. During part of that time, Noah served as “a preacher of righteousness.” (
2 Peter 2:5) As time passed, their wickedness apparently ripened. “God saw the earth and, look! it was ruined, because all flesh had ruined its way on the earth.” (
Genesis 6:3, 12) Their ‘measure of sin was full’; the passing of time had brought their wrong inclinations to full bloom. When God acted he was fully justified. Only eight persons proved righteous in God’s eyes, and he saved them.
The same pattern is seen in God’s treatment of Israel. Despite their having behaved in an unfaithful and depraved way, God had patience with them for hundreds of years. The record says: “Jehovah . . . kept sending . . . his messengers, sending again and again, because he felt compassion for his people . . . But they were continually . . . despising his words and mocking at his prophets, until the rage of Jehovah came up against his people, until there was no healing.” (
2 Chronicles 36:15, 16) The people had reached a point where improvement was no longer possible. Only Jeremiah and a few others could be saved. God could not be called unjust when he finally brought judgment upon the rest."
