I would say yes. The magic rules are unclear for Once.

Cora had no apparent magic and neither did Jonathan (or whatever his real name is), but Zelena was the head honcho in terms of natural, rather than power. Snow and David seem to have a magical child and a non-magical child in the same union.

If Zelena has magic from her child (which shouldn't be possible because the cuff negates the magic within the entire body), then what's to stop her from killing everyone. Regina hasn't used Light magic recently and Emma is gone. That's like sentencing themselves to their doom.
