What an absolutely ridiculous joke of a list. The violence perpetrated by people like Dahmer and Manson is downright microscopic in comparison to the Nuremburg-level crimes every US president since WW2 has routinely perpetrated on the world.
The list doesn't even include Henry Kissinger who, together with Lavrenty Beria and Heinrich Himmler, makes the top three contenders for the "Most Evil Sidekick In Modern History" award. Trump might be a vile POS, but even he doesn't come close to the likes of him.
