On the face of it, that seems ridiculous. During his life, Mohammed was probably responsible for fewer than 20,000 deaths. That makes him a small fry mass murderer, on the scale of Robert Mugabe. And he has stiff competition for the title of greatest mass murderer. It's estimated that Mao Tse Tung was responsible for 80 million deaths. And Attila the Hun is estimated to have been responsible for the death of 1 in every 5 people alive in his time. So, how can Mohammed even be considered to be in the running for greatest mass murderer of all time?
Well, no mass murderer kills all the people whose deaths he is credited with. His total includes all the people who killed under his influence. And that's how Mohammed gets in the running. While no one is killing in the name of Mao and Attila any more, people are still killing in the name of Allah, and so their total gets credited to Mohammed. Members of the cult of Islam have been killing in the name of Allah for almost 1400 years. Most of those years probably added only a few thousand deaths to Mohammed's total. But, it is estimated that Tamerlane killed 1 in 20 people who were alive in his time, in the name of Allah. And Mamhud of Ghazni killed indiscriminately as he began the invasion of the Indian subcontinent by the cult of Islam. That invasion alone would have added millions to Mohammed's total.
I haven't tallied his total, but a rough estimate puts him in the millions of deaths, and thus in the top ten mass murderers of all time. And, because as long as the cult of Islam continues to be a death cult, with killing religiously blessed, we can be sure that Muslims will continue killing in the name of Allah, his total will continue to increase. What's the total deaths tallied to Mohammed just this year? It must be in the thousands. And so, because a monotonically increasing series tends to infinity, we can be assured that if Mohammed isn't yet the greatest mass murderer in history, eventually he will be the greatest mass murderer in history.
