I think you meant figuratively, not legally. Because legally withholding aid is not killing someone, as has been established by a few hundred years of common law.
You also have to remember that pharmacies fall under ambulatory care, not emergency medicine. In other words, they're for if you're healthy enough to move about (very generally speaking what falls under ambulatory care is very complicated). If you are literally dying, go to the hospital. Beyond that... while that situation would suck, not having ready access to a pharmacy is a constant problem for millions in the US, esp when you get into the huge states with low populations. There are plenty of small towns with nothing even remotely close that only have a single pharmacy, and if their insurance doesn't cover it than their choices are pretty limited. This is the basis for how mail order pharmacy started to expand.
