Based on data from above.According to University of Hawaii political scientist Rudolph J. Rummel,1 the total number killed in all of human history is estimated to be about 284,638,000. Of that number, 151,491,000 were killed during the past 100 years. The single largest killer in all of human history is, by far, atheistic Communism with a total of 110,000,000 … over 1/3 of all people ever killed! If we add to that number just two other regimes where religion of any sort was strongly discouraged, Nazi Germany and Nationalist China, the number rises to 141,160,000. Almost 50% of all the killings in human history were committed in the past 100 years by regimes that either actively promoted atheism or strongly discouraged religion. We have not considered the over one billion abortions, where Christianity seems to be particularly unwelcome. When the murders of history are tallied up, it is very clear that atheism is the most dangerous philosophy ever embraced by humanity. The most effective restraint on mankind's inherently evil tendencies is faith in God through Jesus Christ, a faith that actually follows the teachings and commands of Jesus Christ as a daily way of life
