Book of Mormon: The Prophet Mormon Contrasts to Make Points Obvious about the Order of Nehors People of Ammonihah in Alma 16

In recounting the Lamanite attack, Mormon splits the account into two strongly contrasting parts: the people of Ammonihah, and the people of Noah.
First, here’s the account:
Alma 16:2 For behold, the armies of the Lamanites had come in upon the wilderness side, into the borders of the land, even into the city of Ammonihah, and began to slay the people and destroy the city.
3 And now it came to pass, before the Nephites could raise a sufficient army to drive them out of the land, they had destroyed the people who were in the city of Ammonihah, and also some around the borders of Noah, and taken others captive into the wilderness.
4 Now it came to pass that the Nephites were desirous to obtain those who had been carried away captive into the wilderness.
5 Therefore, he that had been appointed chief captain over the armies of the Nephites, (and his name was Zoram, and he had two sons, Lehi and Aha)—now Zoram and his two sons, knowing that Alma was high priest over the church, and having heard that he had the spirit of prophecy, therefore they went unto him and desired of him to know whither the Lord would that they should go into the wilderness in search of their brethren, who had been taken captive by the Lamanites.
6 And it came to pass that Alma inquired of the Lord concerning the matter. And Alma returned and said unto them: Behold, the Lamanites will cross the river Sidon in the south wilderness, away up beyond the borders of the land of Manti. And behold there shall ye meet them, on the east of the river Sidon, and there the Lord will deliver unto thee thy brethren who have been taken captive by the Lamanites.
7 And it came to pass that Zoram and his sons crossed over the river Sidon, with their armies, and marched away beyond the borders of Manti into the south wilderness, which was on the east side of the river Sidon.
8 And they came upon the armies of the Lamanites, and the Lamanites were scattered and driven into the wilderness; and they took their brethren who had been taken captive by the Lamanites, and there was not one soul of them had been lost that were taken captive. And they were brought by their brethren to possess their own lands.
9 And thus ended the eleventh year of the judges, the Lamanites having been driven out of the land, and the people of Ammonihah were destroyed; yea, every living soul of the Ammonihahites was destroyed, and also their great city, which they said God could not destroy, because of its greatness.

The unrepentant, wicked Ammonihahites are destroyed—every single one of them—in one day. They rejected the words of Amulek spoken by the spirit of prophecy:
Alma 10:20 And now I say unto you that well doth the Lord judge of your iniquities; well doth he cry unto this people, by the voice of his angels: Repent ye, repent, for the kingdom of heaven is at hand.
21 Yea, well doth he cry, by the voice of his angels that: I will come down among my people, with equity and justice in my hands.
22 Yea, and I say unto you that if it were not for the prayers of the righteous, who are now in the land, that ye would even now be visited with utter destruction; yet it would not be by flood, as were the people in the days of Noah, but it would be by famine, and by pestilence, and the sword.
23 But it is by the prayers of the righteous that ye are spared; now therefore, if ye will cast out the righteous from among you then will not the Lord stay his hand; but in his fierce anger he will come out against you; then ye shall be smitten by famine, and by pestilence, and by the sword; and the time is soon at hand except ye repent.

Of the other Nephites that are taken by the Lamanites (likely to be sacrificed), not one soul is lost—they are saved by the words of Alma spoken by the spirit of prophecy.
