The idea of a “right to life,” while appealing, is highly suspect. “Rights” are the highest order of human entitlements, things which one can reasonably expect will never ever happen to them, and which if violated represent a colossal failure of our moral and legal infrastructure. In reality, people die all the time for a variety of natural and artificial reasons, and while we certainly think that these deaths are unfortunate, we don’t think that someone’s human rights were infringed upon every time someone dies in a motor vehicle accident. By contrast, we do have an actual right not to be murdered. When one human being deliberately kills another human being, we rightly see that as an exceptional and grave violation of a basic human right. Therefore, it doesn’t violate anyone’s rights to let the five people die, but it certainly does violate the right of putative sixth person to actively murder them to save the others. Moreover, it may be questionable to assume that all lives are equally valuable; if we are going to engage in the grisly business of actually summing up human lives, why treat someone who we’d expect to only live for another year equal to someone we can expect to live for another sixty? If the advocate of killing the one is going to adopt a “maximizing” ethical view, they should at least commit to a true utilitarianism, rather than a view that is not necessarily supported by either utilitarianism or deontology; treating all deaths as equal, regardless of much they cut a life short, is not something a utilitarian would get behind.
