Having watched the suffering of those who believed on their words, Amulek honestly wonders if they would be next. Alma, however, understands that their work is not finished. That did not mean that they would have it easy, however.
The chief judge of the land of Ammonihah expects that Alma and Amulek would be subdued, if not scared, by witnessing the destruction of so many people. Therefore, he can ask: “after what ye have seen, will ye preach again unto this people, that they shall be cast into a lake of fire and brimstone?” His question suggests that the particular form in which the righteous were killed was designed to mock Alma’s prophecy of fire and brimstone for the wicked.
Note that the concepts of what a judge might do according to the law is different for Ammonihah than what we would expect. The judge himself mocks Alma and Amulek in both words and by physical intimidation. Mormon reminds his readers that this judge, and by extension, all of Ammonihah, was part of the “order and faith of Nehor.” In case his readers have forgotten, Mormon makes certain that we remember that Nehor slew Gideon, and, therefore, we should not see this order and faith favorably.
