Seraphim's JOB is to be an extension of his psyche. The idea that these parts of your psyche are part of a larger organization (ever represented by someone that is in realife very close to me) is that i feel that our sense of morals is something that is very much fasioned by the society we live in, mixed with our own personal feelings, and indeed sometimes a sense of free will. There are no real rules, just how we each interpet them - it's called free will.
as far as seraphim possibly knowing things piro doesnt, sure, that is very possible - often we ignore or refuse to accept things we should, and they become part of our moral background, just waiting for the right moment to 'click' and come out, at which point we might ignore them...
Also (in particular with me) you have to take everything the author says with a grain of salt. My views about what im doing are no less colored than everyone elses :) Lets just say that the whole conscience world operates on the same principles as Hobbes Biology, if you catch what im talking about :)
