Not only does moral nihilism distroy moral life by rejecting all of moral principle

furthermore

it rationalizes the logic of nihilism morality through relying on some philosophical conception and ulteriorly makes this logic infiltrate through life area and control the thinking and behavior of people.It is the most typical representation that moral nihilism replaces the morality and life into value through the value logic of modern axiology and gives denial to thing-in-itself and universal significance of morality.Therfore

the morality has to fall into extreme relativism

till nihilism.
