Hitler destroyed his country. Mussolini didn’t actually make the trains run on time. Stalin, Lenin, and Mao killed millions just because of their supposed class identity. Putin invaded Ukraine and thereby caused hundreds of thousands of Russian and Ukrainian casualties without accomplishing much. Orban’s Hungary is poor and corrupt. Oh, and Trump started a war against Iran because his golden gut told him it was a good idea.
That’s what you get when you give uncontrolled power to people who are only too inclined to misuse it.
