Can you provide examples of the double effect principle in ethical decision-making?

The double effect principle is a moral concept that allows for a harmful outcome as long as it is unintended and outweighed by a good outcome. An example is when a doctor administers pain medication to a terminally ill patient, knowing it may hasten their death, but the primary intention is to alleviate suffering. Another example is when a soldier unintentionally harms civilians while targeting enemy combatants in a war zone, with the primary goal being self-defense or protecting others.
