One of the common questions regarding Bigfoot is if it is evil and where did it come from? While alot of these questions regarding where the creature came from and its evolutionary history will only be discovered for sure when science has a specimen to study.
However several theories exist regarding the question on if Bigfoot is evil. Nearly all ancient native american legends regarding Bigfoot tell of a savage, aggressive and evil beast. Variously telling of the beast being a cannibal or being an evil spirit that brought sickness and misfortune upon mankind when their paths crossed.
We will cover more legends regarding Bigfoot later but for now we will cover one specifically: The Potawatomi legend of the Windigo/Bigfoot (many Great Lakes tribes had similar legends but for brevities sake we will only cover the Potawatomi one). The legend tells of a monster who would attack the Potawatomi in winter time and devour them, he was described as being a giant who had an all-consuming hunger yet the more it eats the less satisfied it would become keeping it continually hungry. The Potawatomi only were free of fear of the Windigo/Bigfoot in the summer months as the beast did not like warm weather, only the most powerful shaman were said to beable to defeat the monsters becasue their size and strength made them impossible to kill with normal weapons.
As you can see from the legend above Bigfoot was regarded as a evil, aggressive beast who has terrorized mankind going back all the way to when primitive native americans inhabited all of north america. So is Bigfoot evil? Most definetly...time and time again it has been proven they are savage dangerous animals.
