Comics are B-canon. Canon until the show does something differently. That "black mist" was a manifestation_*from_* Luna's hatred/generic magic transformation effect. Not a sentient creature.

> Plus, if NMM was "all Luna", then it would mean that she_*willingly_* tried to kill her own sister, and attempted to enact something that would essentially destroy the world. After reading Journal of the Two Sisters, that very interpretation of Luna doesn't sit well with me.[/bq]
Insane people do insane things, who would've thought? The Cutie Re-Mark also showed that not only did she_*not_* kill Celestia (she imprisoned her in the moon as revenge) but that the world continued on despite its lack of sunlight. Show canon > comic canon.

Except everything else in that legend was accurate. Literally down to the day. It would be awfully odd (and convenient for your point) if just that_*one_* point was inaccurate, wouldn't it?

> Plus, Nightmare seems to require its vessel to suffer from a negative emotion. It doesn't matter what that emotion is, as long as it's there inside the pony.[/bq]
You're using comic canon. You can't argue for something by using an example which requires said point to be unquestionably true to begin with. That's basically saying "The proof of this is that this is true."
You left out the part where Luna created the Tantabus to torture herself. She also blames herself and speaks of what she did in first-person. Pretty strong indicators that it was her and not some third-party creature that did what she did. You're proof is "the black ball that surrounded her looks somewhat like the black mist in the comic."
The Nightmare Rarity arc was simply someone going "Hey, wouldn't it be cool if one of the mane 6 was corrupted like Nightmare Moon?" and then they came up with a way to make it semi-believable.
What the Fluff?
