In general, Night is right. If you read the biographies of Necromancers, it becomes clear that they were all once people and are not some original characters from the world of the undead. They are either heroes who returned from the world of the dead for one reason or another, or ordinary mortals who devoted themselves to necromancy and... became immortal :)
so, this is a nonsensical innovation.
The happy people are the ones who have a soul.
I'm complicated
