For example: The Blind Witch (Ginger), gnome, ogre, etc, helped Regina cast the first curse. Zelena didn’t help cast Snow’s curse but altered it, same as Emma with Hook’s. And then Nimue with Hook too. She was the unofficial caster since Hook used her love’s heart to do it but she wasn’t the physical caster. In these cases it's only a matter of ingredients.

In the first curse, one of the ingredients was "a lock of hair from those with the darkest souls". They did not help Regina cast the curse, she forced them to provide her with a single ingredient.

In the second and third curses, Zelena and Emma tampered with Snow and Hook's curses respectively by adding a memory wipe that was not desired by the original casters.

In the most recent curse, Drizella forces Regina to provide her with a single ingredient, much like Regina did for the group of villains for her own curse.

None of these people helped cast the curse. The first and current curses are only ingredients given to the caster. The second and third curses were tampered with by a third party.
