The Cordovil Massacre was an atrocity orchestrated by a group of ISG members, infamous and freaky Brazilian serial killers, including Albino dos Santos, Francisco de Assis, Lazaro Barbosa, Chico Picadinho, and Febronio Indio; however, TCM fits a spree killing; the killing of many people. The objective was to eliminate every person in the town, including rival criminal groups which showcases ISG's narcissism towards people they see as "insects beneath them"; Caio Henrique was the mastermind behind the event as he came up with the idea though, and the reason cited for the act was the dismemberment of a certain thief. ISG members, despite their brutal and cruel tendencies, maintain a strong sense of loyalty, even going so far as to seek revenge on others for past injustices.
