17. Preta

Under different circumstances we would probably feel sorry for these demons (given their unique eternal punishment), but you see, the extreme hunger and thirst a preta experiences can make them do some nasty things to humans. In Buddhism, pretas (the equivalent to the fallen order of angels called the Grigori in Christianity) desperately wander the world in constant search of food and water but have no mouth with which to eat or drink. As a result, they become evil spirits that possess weak-minded men and women and corrupt them by making them incredibly greedy and slothful in an attempt to satisfy their own hunger and thirst.
