We have to consider Neji's feelings about his own death and how he felt like he was making a positive choice instead of having his life robbed from him. He stated that Naruto held his life in his hands as well as so many others, including Hinata's. Neji did not regret death, so why should Hinata act like his last action as a living being was not positive?!?! We have to consider the fact that this whole thing is a story, so the ways that meaning and character development are dealt with are a bit different than reality. It has been three of our years since the war started, three whole years of no real breaks, no real laughing at the ramen stand, no real joy of the Konoha 9 bantering and playing, no sexy jutsu with Konohamaru, etc. So if we as readers have a situation with no opportunity to bring about elements of love, joy, comradery, and general growth of the characters on their more human sides because we are trapped within a war setting for so long then there will probably be odd seeming situations, like love growing deeper on the battlefield. When Naruto is fighting and feels his way of ninja being lost, Hinata is there to help him realize how strong he is ( when Naruto fought Nagato ) is that not the same thing Naruto has done for her?!? Also, if her life is in his hands, then it is appropriate for her to comment on his hand as a literary trope. She has always seen Naruto for something amazing, she sees what others only see later and so for her to acknowledge that his hand is big ( big enough to carry the hopes for all of their world!) it might be a metaphor. As far as grotesque goes, Shigurui or Gantz or Berserk might be more apt examples of something that is grotesque, transgressive and terrifying...Naruto is like all cutesy stuff..
