It has been fully one century since the Communist Party seized power in the Soviet Union. According to records compiled by the U.S. Congress, communist regimes were responsible for the deaths of at least 100 million people.  The Black Book of Communism details this history of murder. 
From documents declassified by the governments of nations in the former Soviet Union and Eastern Europe, as well as official records on the victims of communist political campaigns in China and North Korea, the public has gained a good picture of the Communist Party’s addiction to killing.
Communist totalitarianism is often compared to that of the Nazis. While there are many parallels to be found, there is one crucial distinction that is often overlooked: The Nazis aimed to eliminate the Jewish people, but the goal of communism goes beyond physical slaughter.
People of faith do not consider physical demise to be one’s true death, since the soul goes to heaven or is born again in the cycle of reincarnation. The Communist Party uses killing as an instrument to plant the seeds of terror in the minds of the people, forcing them to accept its evil ideology. Through the destruction of morality, people’s souls are fated to damnation. The Communist Party aims not just to destroy man’s physical body, but also to destroy his soul.
An additional characteristic of the Communist Party is the intensity with which it carries out internal purges and selects for the cruelest of leaders. It is difficult for many to understand the rationale behind the barbarity inflicted by the Communist Party upon its own ranks, including those who became victims simply for deviating from the Party on specific issues, while otherwise being wholly loyal to the Party and its leadership.
One reason is that the Communist Party, in its rebellion against gods and humankind, possesses an instinctual fear that its doom is always around the corner. To reinforce itself, the Party needs to recruit individuals with no regard for moral right and wrong. These individuals are distinguished in the process of mass killing, and their elevation to positions of leadership enables the specter of communism to ensure the perpetuation of its earthly tyranny.
In 1989, the Chinese Communist Party (CCP) cadres who refused to participate in the June 4th Tiananmen Square massacre were purged. Jiang Zemin, who demonstrated his cruelty during the events, was promoted to become leader of the CCP. After Jiang began the persecution of Falun Gong in 1999, he promoted officials such as Luo Gan and Zhou Yongkang to high positions, as they had demonstrated their ability to commit the most brutal crimes in the persecution.
Another motive for killing is to recruit participants from general society, as was done during the Cultural Revolution. By committing murder and other crimes, the masses implicated themselves as accomplices to the CCP’s savagery, and the most brutal perpetrators became the staunchest followers of the Party. Even today, many former Red Guards who committed assault and murder during the Cultural Revolution express no remorse for their crimes, saying that they have no regrets about the events of their youth.
Furthermore, by killing its victims openly and deliberately, the Communist Party cows the general population into obedience.
All this allows us to expound on a general principle: Throughout history, killing has occurred under tyrannical governments or during times of war because there was an enemy to be defeated. It is the characteristic of the Communist Party that it must have an enemy, and if there are no enemies, it must invent them so that it can continue to kill.
The introduction to The Black Book of Communism provides a rough estimate of the death tolls of communist regimes around the world. It verified a figure of 94 million, including the following:
20 million in the Soviet Union
65 million in China
1 million in Vietnam
2 million in North Korea
2 million in Cambodia
1 million in Eastern Europe
0.15 million in Latin America (mainly Cuba)
1.7 million in Ethiopia
1.5 million in Afghanistan
10,000 due to “the international communist movement and communist parties not in power” 
Apart from Russia and China, lesser communist regimes have shown themselves no less willing to engage in absolute evil. The Cambodian genocide is the most extreme mass murder carried out by a communist government. According to various estimates, the number of Cambodians killed by Pol Pot’s Khmer Rouge regime ranges from 1.4 million to 2.2 million—up to one-third of Cambodia’s population at the time.
Between 1948 and 1987, the North Korean communists killed more than 1 million of their own people through forced labor, executions, and internment in concentration camps. In the 1990s, famine killed between 240,000 and 420,000 people. In total, 600,000 to 800,000 North Koreans are thought to have died unnatural deaths between 1993 and 2008. After Kim Jong Un came to power, he committed more flagrant murders, with the victims including high-ranking officials and his own relatives. Kim has also threatened the world with nuclear war.
In just one century, since the rise of the first communist regime in Russia, the evil specter of communism murdered more people in the nations under its rule than the combined death toll of both world wars. The history of communism is a history of murder, and every page is written with the blood of its victims.
