squeak, how does the halacha apply if the person (call him A) who prevents the other (call hm B) from living is the one who put B in the situation in the first place. In your analogy, if A ties up B & B starves to death, what is the halachah?
Although since one of the 7 Noachide laws is to set up courts, I’d say regardless of the halachah, the relevant point should be what US law has to say about it.
