Question

Quizplus · Accepted Answer

The principle of double effect can justify the pain caused by drawing blood for a diagnostic test because it acknowledges that a harmful effect (pain) can be morally acceptable if it is a side effect of achieving a good end (accurate diagnosis). This principle allows for actions that have both good and bad effects, as long as the intention is to achieve the good effect, and the good outweighs the bad.
