The killing kitten was only in Part 2.The amount of SS moments in Part 1 (albeit one sided) alone dwarf the amount of NH moments in Part 1+Part 2 combined
I still think SS is worse in part 1 than NH as well, for the same reasons. Naruto wasn't rude to Hinata and didn't put her down like Sasuke did with Sakura. NH was simply shown as irrelevant, an acquaintanceship at most, while SS was shoved into our faces as negative pretty much all the time.
Naruto's obliviousness toward Hinata it most painful to watch than Sasuke's trying to sever his bonds by being violent and mean.
It's probable that Sasuke has a soft spot for Sakura (not love though) when Hinata is completly out of Naruto's mind. I feel like he only feels pity for her at best. He wouldn't even like to hang out as friends with her. 
Well, that is your opinion, but I will explain mine as well. The 'soft spot' you speak of that Sasuke had for Sakura was because of team 7 (I kinda think Sasuke viewed team 7 as sort of a family in part 1, and Sakura is his annoying sister he isn't too fond of, but cares about anyway). Outside of that bond, it was nothing but negativity. Whenever they had personal interaction, he was always calling her 'annoying' and being cold towards her. He never wanted anything to do with Sakura personally, and he always rejected her. He wanted nothing to do with her outside of team 7, and he never thought of her alone without thinking of Naruto and/or Kakashi as well. Just look at chapter 693, it confirms that he was never interested in Sakura. At least with Naruto, I agree he was oblivious and obviously didn't love Hinata back, but at least he was nice to her on his own accord when they were alone together in that one scene when he said he liked people like Hinata (obviously meaning as a friend, we know what he likes when it comes to romance *cough* Sakura *cough*).
Also, ns.Believe.It and NarutoFireFoxUzumaki, thanks for backing me up. I am done with this subject since it is simply an opinion, and you don't need to argue about opinions.
