Interesting perspective, but they stressed that this was where Dark Magic was born.

I think magic was simply neutral, but Dark magic was magic rooted in Darkness, while Light magic was unknown. I'd say Merlin's magic was neutral.

Then we had things like the Apprentice saying that the Merlin wand had All the light magic (besides what Emma has) and then Emma says it's Merlin's magic.

So, from that I assume that Merlin had all the light magic (that wasn't corrupted by Nimue and dark magicians) in that particular world.
