Duty to rescue
Humanity: the rules of humanity advise that the essence of morality and right behavior is tending to human relationships. Therefore, virtues (desirable character traits) such as compassion, sympathy, honesty, and fidelity are to be admired and developed. Acting out of compassion and sympathy will often require rescue where someone is in need. Indeed, it would not be compassionate to ignore someone's need, though the way one fulfills that need may vary. In cases of emergency, rescue would be the most compassionate act compared with allowing a person to remain trapped in rubble.
