Nah it was supposed to show Bee's compassion. Even though Motoi tried to kill him, he still saved him.the only thing i legitimately liked in this chapter was seeing a younger bee. Other then that this wasn't a very exciting chapter. And also the part with the squid attacking motoi, thought, was completely pointless...
I have a feeling it will be forgiveness that will help Naruto control the Kyuubi, because you have hatred in your heart if you can't learn to forgive (or something corny as **** like that). So Bee was just demonstrating it.
Come to think about it, Bee's never killed anyone. He could have killed Sasuke, yet he tried to run even though he was whooping their asses.
Only Kisame, and that was probably because Kisame would be persistent to take him anyway.
