 Certainly, torturing an innocent person to death is worse than murder, for it involves torture in addition to murder. On the other hand, torture does not necessarily involve killing, let alone murder, and indeed torturers do not necessarily have the power of life and death over their victims. Consider police officers whose superiors turn a blind eye to their illegal use of torture, but who do not, and could not, cover-up the murder of those tortured; the infliction of pain in police cells can be kept secret, but not the existence of dead bodies.
