I would argue that the man who killed the most human beings in history is Fritz Haber. Between breaking the Malthusian Bargain (leading to a massive population explosion and everything associated with it) and creating the means by which high explosives can be created on an industrial scale (and everything associated with it), he's pretty much the single most influential person who's lived since the establishment of agriculture.

Bonus points for: creating the first "true" chemical weapons (in WW1) and his encore, Zyklon B (yes, he created the precursor, not the final product).

BASF is a huge german corporation that produced Zyklon B, the gas used in Ausschwitz to kill thousands of people. They're still going strong. It is by far not the only german corporation that benefitted greatly from the Holocaust. Take IBM for example, they delivered card-computing systems to manage concentration camp popula... Oh shit! IBM is american, my bad.
The Bundeswehr, the german military, was run by Nazi Generals in its early years. Just this year there were several scandals concerning Neo Nazis among their ranks.
A lot of people benefited from the atrocities of the third Reich. Don't kidd yourself. Remember, Hitler hired Ferdinand Porsche to develop the Volkswagen. The development of the VW Beetle was started by the Fuehrer.

Well after a small amount of research it appears that the nazies used Carbon monoxide as well as cyanide. so there goes his large chimney and and sealed room theory ore at minimum his necessity for it.

"homosexuals, physically and mentally disabled, and intellectuals. In early 1940, the use of hydrogen cyanide produced as Zyklon B was tested on 250 Roma children from Brno at the Buchenwald concentration camp.[4] On September 3, 1941, 600 Soviet POWs were gassed with Zyklon B at Auschwitz camp I; this was the first experiment with the gas at Auschwitz.[5]

Carbon monoxide was also used in large purpose-built gas chambers. The gas was provided by internal combustion engines (detailed in the Gerstein Report).[6]"


"The gas chamber at Auschwitz I was reconstructed after the war as a memorial, but without a door in its doorway and without the wall that originally separated the gas chamber from a washroom. The door that had been added when the gas chamber was converted into an air raid shelter was left intact.[10]"

The hate you see in this video has nothing to do with the true teachings of Islam

True Teachings : I never suggested, implied or even hinted ever so slightly that this video represented the "True teachings" of anything. It has an "islam" tag. Thats it. Secondly, "true teachings"= S U B J E C T I V E. Whoever brainwashed these children also thought, just like you do, that THEY, not you, know the true teachings of Islam. If they didnt think so, they wouldnt brainwash their children with it. It matters fuck all what YOU, or most islamic scholars, think is the "true teachings" of islam, its subjective.

I do agree that palestinians truly are oppressed, but so is Tibet, for hundreds of years, but you dont see buddist children in military kindergarten parades shouting Nirvana and Death to China. There is something about Islam that can drive people to this kind of madness, which truly is madness, under ANY circumstances.

Islam has proven to be an excellent weapon, time and time again, to brainwash people into war-mongering zombies. To say that it to you means peace and harmony is fine and all, And I'm willing to admit that its provably more versatile that Zyklon-B, but its still dangerous when used the right way.
