I see this, as a typical question coming from a person being hit by mass-media anti-communist propaganda, that is of course very common in any capitalist country. As a person also brainwashed since the first day on earth, I know all this propaganda and was convinced of it long time. So I know what you mean. Its I guess the “the mass-murdered people” of Stalin or Mao etc. .
But if you do your research, you will find, that most of the killed were finally killed due to capitalists wars or their influence. After the October revolution 1917 which had hardly any deaths at all, the real mass-murder began with the invasion of about 7 (?) western countries in Russia, called the “Entente” - this name Entente has been used by historians also for others in order to provide some confusion about this widly censored invasion and war against the young Soviet Russia. The term “Soviet”, which is here regarded as simply something bad, actualy means worker councils, i.e. a democratic institution where the people bring in their wants and opinions about politics.
Since the war against the young USSR was not successful, they changed their strategy to financing and organizing a civil war in the Soviet Union with old Tzarists, capitalists, rich farmers or simply dumb mercenaries. They burned down fields of the socialist farms, their machinery and killed lifestock and people, and all these deaths of war and hunger was - of course - result of the “revolution”, result of “communism”, the “mass-murderer Stalin”, who defended the first state of workers and farmers, which because of this had the hammer and sicle in their national emblem. The communists gave the land (of Feudalists and rich big farmers) to the workers who worked on their farms under normally sclave-like conditions, gave them education, self-ruled big (collective) farms with modern land machinery, where they had free housing, food, healthcare, holidays, insurances, education - the typical measures taken in all socialist countries.
Sure, Stalin was not a dumb man, he did know, if they will not develop from a mainly acricultural land to a modern high-tech nation, they will be killed sooner or later by the capitalist countries, namely the capitalist in Germany, who already had a problem with the German people’s socialist revolution in 1918, when workers wanted to stop capitalist wars by ending capitalism.
So the German capitalists founded the “Antibolshevist fund of the German industry” in 1919, hired hungry soldiers to kill all the socialist movement in whole Germany - about 150 bigger towns, socialist Bavaria and fighting the people in the Ruhr region till 1923 with their private army, called “Freikorps”.
This military war against their own people has been complemented by founding NAZI propaganda and NAZI parties like the “Deutsche Arbeiter Partei” DAP, since Feb.1920 renamed to NS-DAP, National-Socialist-DAP. Even a German Socialist Party (DSP) has been founded by the capitalists, namely on initiative of Dr. Paul Tafel, a board member of the Bavarian Industrialist association, who used his nationalist foreworker, Anton Drexler and some railway workers of him and a Journalist in his noble THULE Society with an faked “worker association” who did meet in the Munich Luxuary Hotel Vier Jahrezeiten. This fake-Socialist and fake Worker party (also the party program has been written by Dr.Paul Tafel) obviously should create confusion with real Socialists and give the people a fake version of what they want, which however is under their control. Of course Hitler’s main goal was anti-bolshevism, which means anti-socialism - despite having Socialism in their name! The first NAZI concentration camps were not filled by jews, but were filled with communists. Some proof for this with original German souces can be found in German language here:
Wie Hitler von der Deutschen Wirtschaft an die Macht gebracht wurde.
Regarding “mass-murderer Stalin” I needed to write more, but can not today. So I suggest read what he did write itself, in order to learn what - especially marx-related views - was in his mind. May be
http://www.marxists.org has all of his written speeches and papers to any issue and time. Reading a persons books is a good way to understand their thinking and personality. At
Books - The Revolutionary Communist Progressive Labor Party there is normally no-where found books about him - even from an former Stalin enemy. Sure, Stalin did know that Hitler has been created to crash down Russia in a war and he had to prepare his country for a war, in opposite to a lucky free people country, who enjoy consumption and their life without exploiters and foreign and internal enemies. Possibly, I do not know it, if he really did make some decisions in these deathly times, where even good communists were killed or did die because of this finally. He had to be a hard man for hard decisions. In war times also capitalists countries switch to the so-called “war communism” (as used in Britain) where the government is controlling the whole country to be fit for war.
In order to come back to your initial question: 1. Finally the “deaths of communism”
are the same persons as “the deaths of capitalsism” - or in Russia in addition even the old Tzarists and its exploiting establishment. It was a struggle between communism and capitalism/feudalism. The deaths are from both sides. And 2. : Fascim is a child of capitalism and the rescue mode of capitalism, in case the people tend to Socialism - as 1918 in Germany, in Hungary, later in Spain or the people’s front in France, which led to the intentional defeat of the French army generals during the NAZI attack on France. They wanted and needed the NAZIs to save their economic power. The real background about the BLITZKRIEG so far. There are endless stories behind the history they tell us in mass-media. Any lies of war propaganda which were used to make the wars, later become “history” which is forging our minds and opinions, our basic view of the world. I do not know if the book “The people’s history of the world” of an author’s name (Chris Harman?) I forgot, is a good book, that tell’s it all. But I wanted to give you the idea of a totally different view of the world and history is there or could be written, if there were financial power behind it - which of course is not the case. The powers behind US/NATO governments are not interested in democracy, but money in their wars, killings, fake up-rises etc. just watch some samples how they did it: Economic Hitmen-Ausschnitt Iran-Umsturz:
ZGA - Bekenntnisse eines Wirtschaftskillers Teil 1 (Deutsche Untertitel) or
how they organize their fake-revolutions, “up-rises” or faked “civil wars”:
They know how to attract and fool young and nice youth and make it a fashion action - this is better shown here:(Ivan Marovic Fashion sexy revolutions paid by USA)
For learning how they create terrorists and terror attacks see: title should be "Galdio the NATO's secret NAZI army"

Oh, I forgot your last question: “How many people Che Guevara had killed?” To make it shot: He did not kill “people” at all. He killed US-paid mercenaries or soldiers hired by the dictators or rulers of South-American countries, which were set up by USA. He was and could stay a minister in Cuba and have a happy life as loved by all Cubans, but did decide to stop the terrible conditions in South-America by offering his medical and rebel knowledge and finally his life. Search for “Iran-contra affair” and “Oliver North” to find one of the many examples how USA financed (with drugs!) mercenary troops that fight for US profits in South-America or see how US companies control governments and kill presidents not only there.
