And why would I even care about all the things I'll supposedly accomplish? It will happen when it does.
If that thing, whatever it is, comes to harm humans, then I'm not going to get back at it out of revenge. I'll do it to protect them. Because isn't that the reason of being a shinigami in the first place? To protect?
At least, that's what Rukia keeps on harping about. One of the things.
