Elephants
Maybe it is just me but I have always found Elephants to be incredibly cute. Unfortunately, any time you weigh between 8000 and 13000 pounds, there is a chance you will be dangerous.
These massive beasts regularly run rampant in Indian villages with many instances of the males waging attacks throughout the night with results in destroyed homes and human deaths.
In one village it is estimated that Elephants were responsible for more than 300 human deaths over a 4 year span. This is a similar trend in other villages as well.
