Moral indifference, as the lack of good or "mediocre evil", is essentially a question of how to treat others. In the case of moral indifference, moral indifference ignores others and even regards others as inhuman. The "three-step killing method" in death camps is a typical example. The first step is to cancel the legal personality of the person. In common law, specific crimes are subject to specific and predictable punishments. Death camps abandon the general legal system, and victims may be arbitrarily arrested and executed without making any mistakes. Because civil rights are destroyed, innocent victims "can't prove their crimes, so they can't get some kind of' measurable punishment', thus being completely exposed to arbitrariness and facing complete and endless punishment". The second step is to destroy people's moral personality. This is mainly achieved by making martyrdom impossible. When people are faced with a dilemma, this dilemma is not a choice between good and evil, but a choice between killing and not killing. How to choose? When the Nazis allowed a Greek mother to choose which of her three children was killed, how did the mother choose? By choosing between killing and not killing, the SS, who supervised the concentration camp, successfully destroyed any form of human unity and also destroyed human conscience. The third step is to destroy people. If the legal personality is abolished and the moral personality is destroyed, then the destruction of personality is almost always successful. The essence of human beings is innate, that is, the ability to create new things outside their own resources, which is the essence of human freedom. Once this ability is destroyed, the victims lose the ability to act spontaneously or resist the terrible fate imposed on them. The concentration camp took a man's own life and proved that nothing belonged to him, and he never belonged to anyone. "His death only confirmed the fact that he never really existed." Through these three steps, people's legal personality and moral personality have been abolished, and people's capacity as human beings has been destroyed. People become redundant, equal to animals, even worse than animals, just a "thing". It is precisely because the other is dehumanized that the morally indifferent person can completely turn a blind eye to the suffering of the other. Therefore, killing each other is equivalent to killing animals.

So how should we treat each other? The other is another self, and the relationship between the self and the other is an imaginary intersubjective relationship. This is Lacan's viewpoint in his "mirror stage" theory. From the beginning, I was an Other, a paper net, a master of www.homelunwen.com, born with the help of the Other. In the subsequent relationship between imaginary subjects, the subject's self is established by relying on the other at the other end of the imaginary axis. The ego cannot exist independently, and the other is always an indispensable part of the imaginary relationship. This is the fundamental dependence of the self on the other. Levinas also believes that the other does not appear in the nature of restricting and denying my freedom, but only interrogating my freedom. There is no doubt that others may exert violence on me and at the same time make non-violence possible. Therefore, the relationship between self and others is not antagonistic or violent in nature, nor is it a simple peaceful relationship. In this relationship, the ego must choose between violence and peaceful existence. When the ego meets the other, the ego and the other form the same world. The self and the other are interdependent and mutually constructed, and the complete and true self cannot be separated from the other. The construction of self-identity needs to treat the other seriously and start an effective and continuous dialogue with the other.

In a word, moral indifference is indifference to others, which is not only not conducive to people's survival in differences, but may even become an accomplice of evil, thus threatening the survival of the whole mankind. To build a harmonious society, we should not only crack down on evil, but also cut off the morbid nerves of moral indifference.
