At the end of Gretel and Hansel (2020) (2020), Gretel is walking in the woods explaining that she can choose her own path, good or evil basically. The last thing we see is Gretel's fingers turn black, like the witch's fingers. It doesn't appear that Gretel is fully surprised by this.
Did her fingers turn black because she has chosen the evil path (or the evil path has chosen her), or did they turn black because she has accepted her powers regardless of her desired alignment?
I don't recall seeing the witch's daughter's fingers be black though we know she was evil.
