|This list contains names and relevant details of various atheistic murderers, including genocidal/democidal dictators, mass shooters, serial killers, etc. It was composed to correct the notion that "atheists have never killed anyone" that some atheists have tried to argue and that all violence is somehow due to religion/theism. It has often been observed that when atheists make such a claim and are shown evidence to the contrary, they modify their argument (in a manner of the "No True Scotsman" or "Moving the Goalposts" fallacy) by insisting they meant, "No one has ever killed in the name of atheism," as this still attempts to pin down something that makes atheism look morally superior to religion/theism which supposedly cannot make the same claim. However, it could be argued that no one has actually killed in the name of mere "religion" or "theism" either but rather in the name of specific religious and theistic ideologies. Likewise, many have also killed in the name of specific atheistic ideologies, most famously, Marxism, which was the very reason why many murderers listed here committed their crimes (i.e. to rid the world of religion and of people seen to oppose "Communism"). Many non-Marxist atheists are listed here as well, diversely discrediting the absurd notion that all violence somehow springs from a belief in God (and thus gives credence to the idea that atheism does not necessarily inhibit humans from killing each other but may, as some of these examples could suggest, do the opposite).|
Vladimir Lenin (1870-1924) a.k.a. Vladimir Ilyich Ulyanov
Atheist leader of Communist Russia (and the Soviet Union), as well as founder of the Bolshevik party.

Later, he seized food from peasants all over the country, which worsened the Russian Famine of 1921 that ended up killing 5 million people.

German Nazi dictator who is responsible for the Holocaust (a.k.a. The Shoah), a genocide that killed 11 million people, notably killing 6 million Jews due to the Nazis' particularly anti-semitic policies. While he would sometimes claim to be a Christian to the religious public, Hitler also declared, "Our epoch will certainly see the end of the disease of Christianity," and claimed that "The Christian religion is nothing but a Jewish sect," and that, "One is either a Christian or a German. You cannot be both." Joseph Goebbels affirmed that Hitler was "completely anti-Christian" and said the best way for them to deter the churches from fighting the Nazi government was to "claim" to be Christian while gradually "strangle any attempt" of religion from interfering with the state. Hitler said that he used the term "God" to refer to "the dominion of natural laws throughout the universe" (and said that he was opposed to "atheism" if it meant denying that). However, he was against any religious conception of God, saying that priests have exploited people's feeling, and that "In the long run, National Socialism [a.k.a. Nazism] and religion will no longer be able to exist together." For such reasons, there have obviously been historians who have classified Hitler as an atheist.
