This is an extremely complex and controversial ethical, legal and strategic issue. Different ethical theories, legal principles and practical experience will give different answers. Here are just some perspectives for reference: 1. Ethical and moral perspective • The utilitarian view may believe that if sacrificing a few innocent people can save more lives or achieve a greater just goal, then in some extreme cases, this "trade-off" may be considered justified; • Deontology or absolute rights theory emphasizes that everyone has inviolable rights, and it is unacceptable to actively sacrifice innocent people regardless of the outcome. From this point of view, sacrificing innocent people is a violation of basic moral principles even if the overall victory is achieved. 2. International law and principles of the law of war • Existing international humanitarian law (such as the Geneva Conventions and their additional protocols) clearly stipulates that military targets and civilians must be strictly distinguished, and intentional attacks on non-combatants are prohibited; • The "principle of proportionality" requires that incidental civilian casualties in military operations must not exceed the clear military advantage achieved. Intentional sacrifice of innocent people is usually considered a war crime, which violates the law and undermines the trust of the international community. 3. Strategic and practical level • From a purely strategic perspective, some people may discuss "tactical costs and benefits", arguing that making difficult decisions in extreme situations may lead to greater victory; • But in practice, allowing the sacrifice of innocent people not only has huge moral risks, but may also intensify hostility, trigger retaliation and more persistent conflicts, while undermining one's own moral legitimacy and international image. In the long run, this approach may weaken public support for the government and military strength, and have a negative impact on strategic goals. 4. Paradox and risk • The thinking of allowing the sacrifice of a few innocent people can easily slide into the dangerous situation of "the ends justify the means", which may sow the seeds for more and more innocent sacrifices in the future; • Once moral principles are violated, it may affect the morale of the army, the credibility of society, and the post-war social reconstruction and reconciliation process. In summary, although there is a discussion of "putting the overall situation first" in some theories, whether from ethical, legal, or long-term strategic considerations, deliberately sacrificing innocent people is extremely controversial and risky. Modern international law and most ethical standards believe that every life has inherent dignity, and sacrificing innocent people often leads to far-reaching moral and political consequences. Therefore, the vast majority of opinions tend to deny this practice and advocate strict protection of civilian safety in military operations. It should be emphasized that the discussion here is only an analysis of this theoretical issue and does not constitute any practical suggestions or encourage behavior that violates international law and moral standards.
