What a fucked up reality this chapter conveyed, but also brilliantly written. The meticulousness and ingenuity of Itto's plan to kill his target was great to see. To spend weeks upon weeks training a dog to dodge arrows so that it can be used against the target takes a lot of time and dedication just to accomplish the assassination. It's a very creative solution.
I feel bad for the Diagoro and his dog. That's the first time he's ever had a friend and companionship in his young life. He grew attached, so it saddened him to have to give up the dog and then see it be killed right in front of his eyes. Kudos to the dog for completing its mission that it was trained to do. It led the target right to Itto. Diagoro helped too by whistling and leading the dog to him. Didn't expect to see a boy his age whistle like a grown man. Haha.
It was sad to see how helpless all those town folks were. Starving while the dude that Itto killed is living in a castle and killing dogs for sport. Even though he killed Diagoro's dog, the dog lead the man to his death in the end, so I suppose they're even.
I wonder why Itto targeted this man? In this chapter, it isn't shown that he was hired by anyone. Did Itto deal out his own judgement on behalf of the starving townspeople? It's interesting to see Itto choosing his own targets instead of being paid to carry out an assassination. He's doing acts of "evil" for the betterment of others.
