Child sacrifice was the practice of killing a child and offering it to a god. In 2376, attempting to dissuade B'Elanna Torres' plan to voluntarily return to the Barge of the Dead to see her mother again, Captain Kathryn Janeway explained that there was a limit to freedom of worship aboard USS Voyager, giving the hypothetical example of Torres wishing to sacrifice a child to the gods as a comparison. Torres found the analogy to be absurd. (VOY: "Barge of the Dead")
