One scene struck me in particular, Pico is seen pleasuring Chico with a dog toy. In my opinion this scene represents a lot about human nature. Pico and Chico represent humans, and the toy is the 7 deadly sins, hate, greed, wrath etc. When we use these sins against other people, it is indeed wrong, but at the same time it's so very right, and feels good too, this is evident in this scene, Chico tries to stop it, but it just feels so good, the deadly sins has it's claws wrapped tight around him.
