Philosophy: Nihilism will degrade mankind.

Nihilism is the philosophy that life is meaningless and there is no such thing as "morals". Presumably, this may be the ultimate form of Atheism, having Atheism deny the existence of a God/Deity. Before we continue on the matter relating Atheism and Nihilism, I will define my view of "God" (I am implying I am a believer). God is more of a concept than it is a physical entity. Loss of faith in God may result from the lack of proof or a loss of moral direction. Having God being a concept than more of an existent entity, it satisfies the fact that God is not physical but metaphysical. Moreover, God is a constant reminder of our morals, humanity and it provides us with a way of life.Now, Nihilism encourages there is no meaning to life, there is no morals. Logically, if you deny life's meaning/morality, you deny God. Hence you are an Atheist and Nihilist. Atheists are bound to Nihilism in a sense. If God is a constant reminder of a person's morals, having deny God as an Atheist will only result in a loss of moral direction. Some unfortunate people become so lost, they are oblivious to their Nihilism. Furthermore, it may lead to the denial of morality overall regardless if the denier started as a believer or non-believer. But let me move on to the claim. Having define Nihilism and Atheism, it is meaningless to live if one were to be a Nihilist. With no moral direction, a Nihilist can do as he pleases regardless if it is hurtful to himself or others. As stated earlier, Nihilists can be oblivious to their own Nihilism so in a sense, they do not realize the repercussions of their actions-- they're unaware from right and wrong. Symbolically, if one is a Nihilist, they are no longer human, but a philosophical zombie. And what are zombies good for? Causing havoc for the humans and roam aimlessly looking for something to prey upon. That is what a Nihilist is: A zombie with its only means to survive regardless of what is morally right.This makes Nihilist abominations to a progressive society. They only mean to survive for if one must live they must become selfish. Selfishness, can result in immorality. How so? Selfishness breeds greed, causing disharmony amongst humanity. Instead of sticking together as a species, selfishness disconnects us all and eventually resulting in morality: The butterfly-effect.Some may argue that that selfishness may not simply be a huge factor in the realization of Nihilism but however, little changes can result in drastic effects. Without moral direction, a selfish person will have only the means to survive, doing whatever is needed even if it results in killing or committing an immorality, similarly as to how a Nihilist would act. In fact how could selfishness not be a trait of a Nihilist? It is only reasonable to assume that Nihilists do not have any sense of empathy/sympathy if they presumably believe they can do whatever they desire. Hence, they're a menace to a progressive society called humanity.For this reason, if the philosophy of a Nihilist is that life is meaningless, then they themselves have no reason to live. Without moral direction, it is likely they will loose sight of their own sense of humanity, thus causing havoc for moral individuals. For a progressive species of what is desire for Humanity, the Eradication of all Nihilist must be the goal of all who share the same ideals.
