 However, one can adopt rule-consequentialism as one’s ethical theory and yet view the immunity of civilians or common citizens and the attendant prohibition of terrorism as very stringent, but not absolute moral rules. Thus Richard B. Brandt and Brad Hooker do not view this immunity as absolute. They argue that a set of moral rules selected because of the good consequences of their adoption should include a rule that allows and indeed requires one to prevent disaster even if that means breaking some other moral rule. Even such a stringent moral rule as the prohibition of deliberate use of violence against innocent people may be overridden, if the disaster that cannot be prevented in any other way is grave enough. (See Brandt 1992: 87–88, 150–51, 156–57; Hooker 2000: 98–99, 127–36). There is thus some convergence at the level of practical conclusions between their understanding of the immunity of civilians or common citizens and the “moral disaster” position outlined above (2.3.2).
