"I'm going to kill myself either way," he murmured blankly, "might as well do it the way that's useful."
This was probably, in a morbid way, the best line in the story. It sums up every sentiment Kakashi felt, and I think it was pretty true to his character (duty to the village, practicality).
I like that you didn't use too much dialogue, because the few times you did it really made the statements POP.
Try not to be creeped out....part of being a great writer is the ability to expand your mind...branching out into an area that seems uncomfortable can be kinda good.
