What "make-believe" theology have I used in this thread? And I'm using "silly lingustic definitions"? If every action of man is "natural" - your definition - then everything from the enrichment of Uranium to the Mars rover is natural. Further, murder is an action of man, and therefore natural under your definition - does that mean it should be permissible?
How do you derive a moral code by which to live? I will try and conform my arguments to that rationale, if possible.
Strictly, yes. We are a part of the system, no matter how much you may want to believe otherwise.

When a soldier kills an enemy soldier, is that murder?

That "moral code" would be a system of behaviors approved / disapproved based on how it supports a social system that is vital if Man is to maximize his chances of survival on this wild planet; and his rights, as an individual. We struck a balance, a long time ago, that resulted in every viable society shunning murder, because it is detrimental to the coherence of any social grouping, thus endangering the viability of each entity in that grouping if the society were to break down.
