If there is no outside objective standard to measure both competing claims against, then the value of these claims are mere opinion — and therein the life devoted to pleasure or racial world domination is commensurate with the life devoted to freedom and selfless service. The honorable Nazi, then, is he who manifests Hitler’s will and your patriotic service to America’s ideal is qualitatively no better or worse than his.
More fully, we must consider Aristotle’s distinction that a Good Man is not necessarily a Good Citizen. If there is no God, then morality is normative — it is dependent upon inclination, convention and agreement. If this relativism is true, then the Good Nazi and the Good Man are identical.
As Dostoevsky so succinctly put it: “If there is no God, then all is permitted.” In a godless world, justice then lies within the interest of the stronger.
Without an Archimedean objective moral law to measure our actions against, we cannot justify Good and Evil because they lie wholly in the world of nomos — opinion and consensus. If there is, however, an unwavering objective moral law, then there must be a moral lawgiver to promulgate such law and we are obligated to observe it. We cannot, however, owe such an obligation to an impersonal force — only to a monumental Personality that can will such law. Without Him, the entire moral edifice collapses in upon itself and we are left to languish in an ethical abyss where morality and law are ultimately utilitarian and capricious.
