The Children

]The Children are the primary antagonists of the horror film of the same name "The Children" - however they are a tragic villain archetype as they have clearly become corrupted by an unseen demonic force (Similar in some ways to the Children of the Corn).

This force turns the children into violent, murderous psychopaths who have an unnatural cunning and skill for torture - they also retreat into the forest and begin to kill off their own parents in gruesome ways, at the climax of the film it is revealed there are hundreds of Children in the forest, suggesting the area has been corrupting youths for generations. (They also appear to take on ghostly traits once possessed, having frostbitten features and unnatural eyes that stare out - deadened and devoid of the usual spark of life.)
