Next Massacre
A mass murderer can be your neighbor, your friend, or even a family member! When a massacre occurs, it's simply too late to bring back the victims that lost their lives! It is up to the neighbors, friends, and family members to report suspicious behavior that may occur to us as well as the authorities. A mass murderer is not born a mass murderer so massacres are not planned from birth, therefore, anyone can be transformed into a mass murderer!

Mao Ze-Dong (China, 1958-1961 and 1966-1969)
The top mass murderer on this list is Mao Zedong. Zedong was the leader of the Chinese Communist Party, and became known as Chairman Mao. He eclipses Joseph Stalin and Adolf Hitler because of the estimated 70 million Chinese, along with countless Tibetans, Mongolians, Manchus, Koreans, Hmong, Uyghurs, and other nationalities' brutal deaths.

Adolf Hitler (Germany, 1939-1945)
Hitler makes an appearance on this list as his bid for territorial conquest and racial subjugation caused the deaths of 43 million people. This included the systematic genocide of roughly six million Jews, as well as various “undesirable” populations.

Joseph Stalin (USSR, 1934-1939)
Stalin is responsible for an estimated 20 million deaths. Roughly 14.5 million of this amount needlessly starved to death, and about one million were executed for political “offences”. At least 9.5 million more were deported (although other reports make this figure about 28 million), exiled or imprisoned in work camps, many of which never returned alive.

Hideki Tojo (Japan, 1941-1944)
Tojo is not always considered to be responsible for the deaths that occurred, because he claimed to be working under the orders of Emperor Hirohito who was granted immunity from war crimes prosecution. That being said, if it was agreed, then he would be to blame for the murder of more than 8 million civilians in China, Korea, Philippines, Indochina, and in the other Pacific island nations, as well as the murder of tens of thousands of Allied POWs and for the approval of government-sanctioned biological experiments on POWs and Chinese civilians.

Pol Pot (Cambodia, 1975-1979)
Pol Pot directed a ruthless programme that intended to “purify” Cambodian society of capitalism, Western culture, religion and all foreign influences. His aim was to create an isolated and totally self-sufficient Maoist agrarian state. Cambodia's entire population was forced to relocate to agricultural collectives, and roughly 1.5 million were worked or starved to death, died of disease or exposure, or were summarily executed for infringements of camp discipline.

Leonid Brezhnev (Afghanistan, 1979-1982)
Leonid Ilyich Brezhnev, the General Secretary of the Communist Party of the Soviet Union during the Soviet war in Afghanistan, is responsible for the deaths of over 1 million Afghans. 5 million Afghans fled to Pakistan and Iran and another 2 million Afghans were displaced within the country. In addition to these deaths, approximately 1.2 million Afghans were disabled (mujahideen, government soldiers and noncombatants) and 3 million maimed or wounded (primarily noncombatants).

Saddam Hussein (Iran 1980-1990 and Kurdistan 1987-88)
Hussein's involvement in the Iran-Iraq War caused the deaths of almost two million people. This included between 150,000 and 340,000 Iraqi and between 450,000 and 730,000 Iranian combatants. Then, when involved in the Iraqi invasion of Kuwait, Hussein became responsible for approximately 1,000 Kuwaiti nationals' deaths. During the Gulf War, it is estimated (with no conclusive figure being reached) that he was responsible for as few as 1,500 to as many as 200,000. It has been confirmed though, that well over 100,000 Kurds were killed or “disappeared”. In addition, roughly 500, 000 Iraki children died due to the trade sanctions introduced during this war. And lastly, following the US occupation of Iraq in 2003, mass graves were discovered which suggest that the total combined figure for Kurds, Shias and dissidents killed could be as high as 300,000.

Idi Amin (Uganda, 1969-1979)
The tally here is between 100, 000 and 500, 000 deaths. This was perpetuated by Amin's campaign of persecution of the rival tribes and Obote supporters, in order to secure his regime. The onslaught was so thorough that in some cases entire villages were wiped out. In fact, workers had to fish corpses out of the Nile to prevent the intake ducts at a nearby dam from becoming clogged.

Genghis Khan (1206-1227)
According to Iranian historian Rashid-ad-Din Fadl, the Mongols (led by Genghis Khan) massacred over 700, 000 people in Merv and more than a million in Nishapur. Prior to this, China had about 100 million inhabitants, however after the invasion was complete, it only had roughly 60 million people. Both directly and indirectly, Ghengis Khan is responsible for over 40 million deaths.

Harry S. Truman (1945)
American leader, President Harry S. Truman is responsible for authorising the use of atomic bombs against the Japanese. In 1945, 6 August, the first bomb was dropped on Hiroshima, and the second was dropped on Nagasaki on 9 August. He was therefore responsible for the deaths of about 120,000 and the fatal injuries over 100,000.
