Communist regimes always kill, but communist China has achieved a truly insane level of butchery

One could fill a library with books about the manifold suffering and death caused by communism’s bloody century. The section on the murder and mayhem visited by the Chinese Communist Party (CCP) on the Chinese people would require an entire wing.

“The Black Book of Communism,” published in 1999 by Harvard University Press, ably summarizes the overall carnage. The editor, Stéphane Courtois, estimated that the total death toll from 20th-century communism approached 100 million. And China tops the list with 65 million deaths.
China: 65 million deaths
USSR: 20 million deaths
North Korea: 2 million deaths
Cambodia: 2 million deaths
Africa: 1.7 million deaths
Afghanistan: 1.5 million deaths
Vietnam: 1 million deaths
Eastern Europe: 1 million deaths
Latin America: 150,000 deaths
