Personally this question boils down to a theology perspective. Looking at the human race, every civilization had a measure of what was good and what was evil, but at the core there was a moral sense that developed it.
Personally I believe there is an absolute measure to which is good and which is evil by which all will need to account. (For an expounding of this please PM me and I would glad to discuss this further on a one on one basis.)
That said, the lines can be blurred or even forgotten if an absolute is not established or not recognized. So I can understand the issue because of that.
To quote ceasar: "what is truth?"
In essence the question of good and evil revolve around that question. If truth is relative, then so is good and evil. With no absolute who can say which is which?
In regards to the original question: I voted yes, and as soon as I find resources to support my stance I shall cite them.
