"Childhood, adolescent and youth cruelty has always been dealt by literature and cinema as an anomaly. The first years of somebody's life are supposed to be the most tender ones, the age of innocence. So cruel underaged people are faced either as monsters or young creatures which hard living conditions led them to cruelty. When we talk about groups of people, explanations are tried to be found in the social contouring.
The protagonists of these movies are either cruel youths or victims of other young people's cruelty. Their motives vary, and the explanations about the cruelty vary as well, according to each director's perspective. Some focus on individuals, others treat violence as a social phenomenon, some go far beyond than that."
