Excellent question, Kathryn! Here are some more:

If I were in a burning building and in one room was a neighbor’s three-week old triplets and in another was your own nine-year old daughter, and I only had time to get into and out of one room safely, who would I rescue?

If I were in a burning building and in one room was the healthy mother of four small children who were utterly dependent on her, and in another were two patients in the final stages of terminal cancer, who would I rescue?

If I were in a burning building and in one room was a research scientist who was making great strides towards a cure for Alzheimer’s and in another room were four heroin addicted fifty-eight year old men who move in and out of the penal system and will likely do so for the rest of their lives, who would I rescue?

If I were in a burning building and in one room was a five-year old child and in another were seven people in comas, who would I rescue?

If I were in a burning building and in one room was a five-year-old child and in another were two older women suffering from advanced cases of Parkinson’s disease, who would I rescue?

If I were in a burning building and in one room were five men and in another were three pregnant women, who would I rescue?

I could go on.

Answers to any of these questions do not justify actually killing anybody or treating anybody as unequal to anybody else precisely in respect to basic human dignity and the right to life (i.e., the right not to be killed or have one’s life used as a mere means to benefit others). In all of these cases, there is no question of my actually killing anyone. The question would be whether I was showing unfair favoritism toward some over others. In answering that question, all kind of things become relevant that would not be relevant to a decision on whther to kill: family ties, the life prospects of the potential rescued beings, the suffering they would undergo if not rescued, etc.
