The moral agent’s decision will not necessarily have such wide-ranging consequences. In many cases, the matter will remain fairly quiet (even if it is reported to the police). Furthermore, this is only dubiously a “killing” if one does not adopt a deontological take on the action; it’s simply a weighing of the benefits of who can be saved. In another sense, branding it as making “killing” acceptable is misleading, because this is not a moral license to commit wanton murders, but instead a sacrifice in a situation with no bloodless answer. Moreover, even if the decision becomes public knowledge, and is defined as killing, people will recognize that the circumstances of having to make this decision were truly exceptional.
