Who is guilty of felony murder in these scenarios?

[True Federalist (진정한 연방 주의자)]

Person B is the only one who conceivably ought to be guilty of murder under the law, and even then he'd have to be a non-celebrity minority to be in any danger of actually being convicted.

Person A would need to be involved in the argument itself to be linked by the conspiracy rationale.

The drug possession and the attempted rape are legally unrelated actions, so even if a prosecutor were stupid and sick enough to charge person D with murder for her self-defense, there's no felony conspiracy to link person C to the "crime".
