The article analyses the problem of exceptional situations which induce a conflict between major moral interdictions, on the one hand, and a responsibility concerning circumstances, on the other hand. Three main strategies that resolve this conflict are: 1) reclassification of action, 2) taking into account circumstances of action that permit to violate ethical norms, 3) making distinction between an active action and an action of nonintervention. Having evaluated this strategies, the author proposes and argues for an alternative solution based on the scholastic doctrine of double effect which makes distinction between the direct result of action which the agent strives for and the indirect result which is provoked but not aimed by the agent.
