If a person in authority must make a difficult decision that may harm others, they should consider the following guidelines:

1. Ethical principles: Uphold core values like respect, fairness, compassion, and justice.

2. Legal framework: Ensure compliance with relevant laws and regulations.

3. Consequential analysis: Weigh potential benefits against potential harm.

4. Stakeholder consideration: Consider the impact on all affected parties.

5. Transparency and accountability: Clearly communicate decisions and rationale.

6. Collaboration and expertise: Seek diverse perspectives and expert advice.

7. Moral courage: Stand by principled decisions despite opposition.

8. Empathy and compassion: Minimize harm and prioritize vulnerable groups.

9. Reflection and review: Continuously evaluate and adjust decisions.

10. Integrity and responsibility: Take ownership of consequences.

Additionally, consider decision-making frameworks like:

1. Utilitarianism (greatest good for the greatest number)

2. Deontology (duty-based ethics)

3. Virtue ethics (character-based decision-making)

Ultimately, guided by these principles, authorities should prioritize the well-being and safety of all individuals involved.
