Their souls aren't there anymore so Narza wouldn't get anything out of them. Azavarn does take a person when he makes a deal, but unlike Narza the person remains functional to "enjoy" their deal.

I can't edit it for a while so let's say when taking their souls failed, she was confused and chose a different human. Or maybe, since she can't actually sense a soul, she just kinda passed em by. That works. 

Narza would go marauding with Athinar :3
