Double Effect Principle

**Definition:** Guideline for determining when it is morally permissible to perform an action to pursue a good end with knowledge that the action will also bring about bad results. It generally states that, in cases where a contemplated action has such double effect, the action is permissible only if: it is not wrong in itself; the bad result is not intended; the good result is not a direct causal result of the bad result; and the good result is proportionate to the bad result. (from Solomon, Double Effect, in Becker, The Encyclopedia of Ethics, 1992)
