I agree with Nostradamus on this. Hinata herself said she was being selfish.
It's not really what she said. But what she did. You see I no problem with Hinata sacrificing her life for Naruto. If that was her only option. For example even though I hate Sasuke, I also admire him for what he did, he actually sacrificed his life to protect Naruto against Haku (in the end Sasuke didn't die but the sacrifice part still remains). But that was his only option. Same thing with Minato and Kushina; jumping in front of Kyuubi's attack was the only option they had.
Hinata on the other hand watched Naruto's fight with Nagato from start to the moment she decided to intervene. No one can convince me she couldn't think of a simple basic plan, that doesn't involve committing suicide.
Same thing with 614/364(episode), Sakura just demonstrated just how easily it is to protect someone. But Hinata can't push Naruto out of the way or grab him and jump of the way or continue to push the flying wooden sticks, you know like she demonstrated that she can.
It gets even more hilarious when Hinata herself says that she's not the only one who's wiling to do that because they are all comrades and Naruto confirms this
Besides that Kakashi agrees with you and Kakashi needs to have a serious talk with Hinata it would do her good

The power of friendship. 
Too bad Kurenai abandoned her team, maybe Hinata would've been a little smarter if Kurenai taught her a little bit.
well i kinda dissagree with you saying that what hinata did was stupid..hinata's father said that the focused atack of the juuby was too much for hinata's and neji's air palms to dodge..so that means what neji did was also stupid?..im not realy cool with some of you bashing hinata here,but if there was another logical and plausible way for her to save naruto without needing to give her life for it,then i would love to hear it
Nu, Neji si-a facut datoria, Hinata e cea care a dat-o in bara. Uite ce-a facut Hinata : I s-a alaturat lui Hiashi si Neji, a zis ca il va proteja pe Naruto. Ia lasat pe Hiashi si Neji sa faca toata treaba, dupa aceia a indepartat si ea un atac si a decis sa isi ia o vacanta. Si Neji a fost cel care a suferit din cauza ei.
