Karl Marx used rationalism to create communism which had ended up killing tens of millions of people in the 20th and 21st century and remains a dire threat in modern world. The Nazis likewise were socialists who embraced rationalism over God. In fact, some of the worst events in history were because of those exercising rationalism. Nuclear weapons for example; the constant threat of nuclear annihilation was invented by rationalists who allegedly were seeking to create a better and more peaceful world. None could ever guarantee that such weapons would not fall into the hands of morally depraved persons in the future who control governments, who have no regard for human life, or even non-state actors. | Karl Marx used rationalism to create communism which had ended up killing tens of millions of people in the 20th and 21st century and remains a dire threat in modern world.
