This is kind of more complicated than you’d think. Mostly because after the industrial revolution the population of the world exploded and there are far more people now than there used to be. For example, the world population today is ~8 billion, while in 1930 it was only around 2 billion. If you go back to the ancient world, the population was only about 300 million people in 1 AD. Now of course trying to estimate a theoretical antediluvian population is kind of impossible since the Bible doesn’t contain any census data until the next book, but if we take the date usually given by Creationists of ~2000 BC then the population would have been between 20 and 70 million. So still higher than Hitler* but not by as much as you might think.
*This is if you only attribute Holocaust deaths to Hitler. Hitler killed many more people than just the victims of the Holocaust and you could make the argument that most of the people who died in the European theater in died as a result of Hitler, and by that metric Noah actually loses to Hitler here.












The reason is because they make so much money off every single patient that even if only a few extra people use their drug it pays for the ad. Most people do just get prescribed what they need
