This is definitely a complex issue, and to be honest, I am not quite sure where I stand on moral relativism and subjectivism, as I have not dealt with it very thoroughly. I think that the question comes more down to the fact that while people are born with a moral sensibility, these moral feelings continue to be molded and shaped by their environments, which in turn creates differences of opinion as to what is or isn't moral.
I am unsure that there are any objective moral truths, other than the fact that some form of moral sensibility is innate in human beings. However, this innateness is also subject to genetic make-up, and the level of innateness, while nearly the same in everyone (minusing environmental influence), can vary from person to person.
I think that we can say that while all values are indeed subjective in a metaphysical sense, we can objectively judge the goodness or badness of an agent's actions by measuring the effects of such actions. Furthermore, we can say that nearly all human beings with a healthy psychology would say that being stabbed by someone is not desirable, and if that is so, we can say that whether or not you choose to perform that action it is wrong, because you would find the act to be equally undesirable if it was done to you. I'm really starting to think that this problem comes down to empathy. Can empathy be used to support the claim of moral truths that are applicable to virtually everyone?
