"You seem to think of demons as irrational creatures," the samurai said with a smirk. "Have you ever met a demon before? Ever spoken to one? Ever heard it's thoughts? Perhaps they are not as evil as they seem." As he spoke, he moved back and forth, pacing. "Demons are very much like humans. They have thoughts, feelings, and motives. Tell me, shinobi, when you take upon yourself a contract and you fulfill your end, do you expect your reward? If you do not get your reward, do you go on a rampage and kill everyone? No..you kill the one responsible, and take your reward by force. It is simple, is it not? And perhaps...the one who freed it was simply looking for their own bargain to make."
