Kakashi and Obito in “Unfinished Business”

Kakashi

Whatever the circumstances, one person alone makes the decisions to keep the team together. That's why we have the rule that says all team members must obey the captain without question. Obito, you have no power. That's why I'm the captain of this team and you aren't.

Then why won't you try to save Rin yourself? It means you have the power to rescue your teammate, isn't that right Kakashi?

Kakashi

If you give in to your emotions for even a moment and fail your mission, you'll regret it sooner than you know. That's why Shinobi have rules. That's why we're taught that we must suppress our emotions. You should already know that.

But Rin, she was so concerned for your well-being that she put together that special med kit for you. She even sewed a protective amulet inside it!

Kakashi

The med kit and medical ninjutsu are great systems that the Hidden Leaf developed to increase the success rate of our missions. But like I told you yesterday Obito, better nothing at all than a useless burden.

Useless burden?

Kakashi

To carry out a mission a ninja must only have tools necessary to the task at hand. Useless things like emotions only get in the way.

Do you really mean that? Do you honestly believe that stuff Kakashi?

Kakashi

[remembers his father] Yes I do.

Just forget it. We'll never agree. We're like oil and water. I'm going to rescue Rin.

Kakashi

You don't understand, Obito. You don't know what happens to people who break the rules.

I believe that the White Fang was a true hero. You're right. In the ninja world, those who break the rules and laws are regarded as scum. But those who would abandon even one of their friends are worse than scum! [Kakashi is shocked] I'm scum anyway, so I'm going to choose to break the rules. And if doing that somehow makes me less than a true Shinobi, then I'll just go and crush all the so-called Shinobi!
