What your top 3 k12 members you rather kill of than neji

[Sage of Doujutsu]

For me it would be sakura, kiba or sai

Shino, Kiba or Choji
Kiba and Choji could carry close to if not just as much weight as Neji. Choji because aside from Naruto he is the purest of the k12 ninja aswell as one of 2 k12 members who have been friends with Naruto since the academy. I think the loss of Choji could have destroyed Naruto emotionally. Kiba as a squad mate of Hinata's and friend to Naruto give them something help each other cope/mourn over. Shino because he feels like an insignificant character.
