The Black Fairy was so poorly written that was never clear what was her darkness about

I think Nimue was possesed by the Dark One curse

And Black Fairy had a corrupted soul, like Regina, Cora, etc

The thing is they made it sound like the Black Fairy created darkness, which was not the case. There was evil in the world long before Rumple was born. The title fits Nimue better, because she created the Dark One curse.

So, the Black Fairy was just another human being corrupted like Pan, Zelena, Jafar. She just took it to eleven

And the funny part is.... she became dark only by ripping a heart. She didn't even crush it.
