I believe there is such a (obviously abstract) thing as morals, but I also believe that moral systems are entirely constructed, rather arbitrary, and not absolutely necessary. I consider morality to be the study and practice of the deployment of power that no one should have in the first place. The elimination of all artificially-created systems of unequal power would eliminate the overwhelming majority of conflicts of interest, and so there would no longer be any application for morality. The remaining conflicts of interest would be as they are for other animals: matters of pure survival, and, therefore, amoral.
My "moral compass" (I actually prefer not to refer to my values in terms of morals because of the connection between morals and hierarchy that I mentioned in the previous paragraph) is oriented around survival, but it is not quite as self-centered and short-sighted as the dog-eat-dog "survival of the fittest" concepts often evoked by the term "survival." My concept of survival is based on an understanding of the interconnectedness of living organisms and the centrality of a healthy environment, and so I tend to oppose measures that are designed to benefit humans, but are environmentally harmful or detrimental to other organisms.
One example is the level of antibiotics usage in the U.S., which has come back to haunt us in the form of resistant bacteria. Perhaps an ecosystem-centric medical model could have prevented this state of affairs, illuminating the fact that a threat to the survival of disease-causing bacteria has implications for those with whom they share an ecosystem (humans).
