Sloth Bear of Mysore
Say what you will about bears, as cute as they can be, they also have the ability to be bloodthirsty monstrosities of nature. During the majority of 1957 in the Nagvara Hills in India, a particular sloth bear had an itch it just couldn't scratch, leading to the deaths of 12 individuals and the mauling of more than 20 others. The tales behind the bear's murder spree range from fantastical to tragic, with some claiming it sought revenge after a young girl it abducted as a mate was rescued. British writer and hunter, Kenneth Anderson, who was responsible for the beast's demise, surmised that the sloth bear had been injured by humans in the past, causing its behavior to violently alter.
