Kakashi's example is better, Kakashi didnt loved anyone but Obito was special to him, and it didnt prevent him from killing rin, Obito even in that situation would never be capable of killing her, Kakashi didnt hesitated at any moment but he still cried because she was a teammate but it was no sign of true love.
He seemed rin a part of the team and his best friend love interest.
I get your point, and I agree with the purpose of the parallel. The thing at play here is my long-admitted bias toward Kakashi. I consider him a far better person than Sasuke, and one who chose the right path much earlier than Sasuke is going to -- assuming he does.
Well, that's exactly what Gaara did.
Gaara turned toward the light, certainly, but I would hardly describe him as having "a song in his heart, a spring in his step, and a kind word for all." Gaara remains aloof and reticent, even if his heart has been transformed. His focus has changed, but not every element of his personality or the experiences that shaped him.
However, I understand the point you're making. I agree that if/when Sasuke is redeemed, his attitude and behavior will be improved by his change of heart. But as it is with Gaara, I don't expect fundamental aspects of Sasuke's personality to ever change, including those that make him a poor match for Sakura. Just my opinion.
Draco was a good person at heart, though. He had been twisted by his parents' ideologue. This made him both elitistic a**hole who looked down on the poor Weasley family, and a racist. But when Draco was given the chance to act out his hatred for muggleborn and team Harry, he could not do it. He talked the talk but the walk he never walked. Draco was mostly talk. When Sasuke was given the opportunity to act out his hatred, he walked the walk. This, I think, is the key difference in Draco and Sasuke. Sasuke was a good guy too, once upon a time, but he has completely different level on bad guy stuff than Draco. It is also my understanding that Draco and Harry made a sort of peace by the end of the books. The Malfoys also flipped sides and redeemed themselves. They weren't that morally vacant to me.
I don't want to commandeer this thread with HP stuff, but I disagree. More than anything, Draco failed because he lacked courage and conviction, not because he was "a good person at heart." Same with his family. They displayed some contrition at the clutch moment because Narcissa loved her son more than anything, and their side was losing. She gambled to assist Harry, but not because she had an epiphany about Right vs. Wrong. In the end, the Malfoys had no option but to switch sides if they were going to continue on in wizard society.
I'm not surprised in the least that someone who sees the best in Sasuke and champions him would have the same opinion of Draco Malfoy. That's exactly why I used Draco as an example. We'll have to just agree to disagree, and that's cool. I will always, always, ALWAYS choose Naruto over Sasuke, and absolutely when it comes down to who is best for Sakura.
