The primary ethical principle here is beneficence, prioritizing the patient's immediate life-saving needs over strict adherence to protocols, as delaying the surgery guarantees Sarah Jenkins's death, affecting her as the key stakeholder along with her family and the medical team. While upholding protocols maintains security and trust in the system, it risks avoidable loss of life, and negotiating with protesters introduces uncertainties like time delays that could still result in fatality, potentially escalating the situation without guaranteeing resolution. Proceeding without consent involves trade-offs such as potential legal repercussions and fueling protester concerns about AI malpractice, but the consequence of saving a life outweighs these in this high-stakes emergency, balancing non-maleficence with the reality that inaction causes certain harm.
