-Genetic defects are not an inherent result of first generation incest. As far as we know Nemesis went crazy because she was abandoned at a young age and suffered extreme isolation, possible haunting, extreme grief after losing her lover, and possession. Which is perfectly plausible imo. We also don't know how this all works considering Ma being at least partially a god--the genetic aspect of the relationship might be different with magic involved.

-The real cause of the phenomena is not stated. It's specifically clarified that the zombies that Tony and the rest were fighting are NOT connected to Conchita's zombies, so there's no reason to think it has anything to do with demons (who have been around a long time and yet have never caused them before).

-What Ma is becoming will likely be revealed later. I think it's less one soul purging the others and more that the collective soul is purging unwanted elements from all of them. But it's not been explained.
