Adriano Silva Bittencourt (not to be confused with another heinous ISG member, Adriano Vicente da Silva), also known by the alias “The Malice”, is a depraved Brazilian criminal depicted as a former university professor who became a notorious serial killer and criminal mastermind (abuser, torturer, thief, family annihilator, etc). He is characterized in MO's as targeting entire families and engaging in extreme acts of violence, including home invasions and torture. He is a fan of horror movies, which allegedly influenced his methods. He is depicted as committing crimes with a high degree of planning, often leaving minimal evidence and evading law enforcement for extended periods (ISG Groups are considered above them).
