In laboratory settings, the use of euthanasia is considered ethically justifiable when it is performed to relieve suffering from a terminal condition. This situation reflects a commitment to humane treatment, ensuring that an animal that is experiencing pain or distress due to an untreatable health issue can be spared further suffering. Euthanasia in this context is seen as an act of compassion, prioritizing the animal's welfare over other considerations.

Other scenarios presented do not align with the justification for euthanasia. Research purposes alone do not constitute a humane reason for ending an animal's life, as it does not address the animal's welfare. Euthanasia due to an aggressive temperament may not be warranted since alternative behavioral management strategies are often available. Lastly, using euthanasia during routine maintenance does not relate to the welfare or suffering of the animals and thus is not considered an ethical justification for such an action.
