14. Delphine LaLaurie
She lived in the 19th century New Orleans, and the only words that can describe her best are “sadistic socialite”. She was discovered when the fire broke in her house, most likely provoked on purpose by the slaves who were tied to the stove. When the firefighters came, they saw that these two slaves are not the only one; the attic was full of people who were used as sort of experiments, some of them in cages, while some of them with their body parts removed. Most of them were dead, but LaLaurie ran away and she was never brought to justice.
