Absolute morality measures ethical questions against a set of unconditional standards, without regard for mitigating circumstances. Absolute moralists believe a fundamental source, such as a deity, sets the benchmark of morality that renders them flawless and ironclad.
An extreme position of absolute morality promotes that an action is immoral even when it is done for greater good. For example, lying is always immoral even if it is done to save a life. Christian theology functions on a graded absolutism when two absolutes are incompatible, and that duty is always to obey the higher power. Historically, governing by absolute morality is favored because it simplifies the creation of laws, obedience to them, and it facilitates the judicial process.
