Don't you guys feel like obito is really annoying? Complening about how kakashi (and now the yellow flash) let rin die? this is the ninja world, he should know more than anyone else that nothing is certain and that death is a ninja's best friend.
I always wonder why he doesn't blame HIMSELF. He was alive after all and he couldn't save her either.
It's doesn't look like rin was meant to be a ninja at all.At least sakura has a personnality
