17. Vlad Dracula
I don’t know about you, but when I was a small kid I was so afraid of Dracula and I was thinking that he would come and take me if I am not behaving well. However, at that time, he was just a ghost-like creature for me, and I was not aware that he was actually a historical figure, a prince of Wallachia, who used to kill people by the method of impalement. Besides this, he also ordered people to be poisoned, strangled, hanged, skinned, hacked, burned, boiled, roasted, nailed in the head, buried alive, and many other ways. It is estimated that he killed around 100,000 of people.
