Ivar Gremes meant well, but he was overthinking it.
Neither the Undead nor the Fairies cared what the Calimshan people were plotting.
For one thing, it was the Undead who had taken in the refugees. If it had been Vera, she would at most have left them an open patch of ground to settle on. She would not have cared whether the humans survived.
The Fairies were naturally a little hostile toward species that damaged nature.
They would not go out of their way to oppose humans, partly because it was not in their nature to hurt people lightly—though perhaps they simply lacked the power to do so. But they would not have shown humans this much goodwill, either.
As for the Undead, they were simply used to it. William had begun training them in refugee management back in Telashir, and after traveling through several worlds, they were practically veterans.
If the Calimshan people took that bare minimum of kindness to mean the Undead were like the Justice Knights, unable to act against civilians outside the Evil Alignment because of some lofty conviction, they were in for a rude awakening.
On Toril, civilians rioting against their government certainly would not count as evil. But by William's standards, attacking an army for personal gain was essentially rebellion. Once they started smashing, looting, and robbing, it became evil.
William applied strict standards when judging rebellion, but once he made that judgment, those people would become Red Names in the eyes of the Undead.
Even if they did not become Red Names, expelling them from the camp and leaving them to fend for themselves would be perfectly normal.
So the Harpers' efforts had saved only the Calimshan people's lives. To the Undead, whatever choices those people made were of little consequence.
