The violence in this show is intermittent, but can be quite extreme. Involves shooting, stabbing, slicing, as well as self-inflicted harm. Characters are killed on-screen with their facial expressions of shock or pain emphasized. Some of the wounds inflicted throughout the show are especially gruesome (e.g. a sword is suddenly stabbed through a man's head and the blade can be seen inside his mouth, a man cuts his own neck open releasing a spew of blood and exposing the flesh inside his neck).
Features violent themes throughout: murder of children and women, bioterrorism, serial killings, human experimentation, mind-control, and suicide.
