The purpose of morality is the furtherance of your life. (I’m sure you’ll disagree with that, but if so, you can disregard what I wrote.) There’s no benefit to honor if you are dead, and anyone putting your dishonor on your family is committing a logical fallacy.
No. The fact of a conflict between morality and life implies a previous breach, but a breach does not necessarily imply there will be such a conflict. A breach runs the risk of it, which is one reason to try as hard as possible not to commit such breaches, but it does not guarantee it. Such a conflict is prima facie evidence that the breach has broken the moral context - not all breaches have that consequence.
No, no more than whatever brought the mother and child to their circumstance breaks the pharmacist out of his moral context. They are separate contexts, (unless the event is part of a larger one, such as the complete breakdown of society or something). The pharmacist still has the right to protect himself from theft. I would question the morality of accepting a job that requires the possibility of such a sacrifice, but that’s a different kind of question.
If you prefer, think “mistake” when I say moral breach. I consider them fundamentally the same class of things (with various species), but I have a much broader definition of morality than most people, so it’s understandable if you disagree. Even mistake might sound too severe for you, but understand that my meaning of it is “not the correct action for the circumstances”. And, as I said before, neither one automatically implies blame - the opposite of “moral” is not necessarily “immoral” as the term is commonly understood. Not having enough lifeboats to account for the whale eating some was not the correct action for the circumstances, by definition, since the whale did eat them and left you in the lurch. It may have been completely rational to not take more boats, it may have even been irrational to take more, nonetheless, the reality is that it was not the “correct” decision in the end.
Think of it this way, you have a map of an underground cave complex. The map is like a moral code, it helps you figure out the way to get where you want to go. You’re walking around, and realize you made a wrong turn somewhere, so you no longer know where you are. There’s no indication of what part of the cave you are in, so the map is suddenly no help. The map (you’re moral code) no longer gives you any basis for deciding to turn right, turn left, or go straight. But you have to go somewhere. Flip a coin, pray, dowse, whatever, but it’s no longer a question of the “moral code” map guiding you through the cave. The immediate goal then is to get your bearings as soon as possible, but until you do, you have no guidance. to your actions (at least not from the map).
