No not really all you said right now is compeltly interchangable with any other villain, circusntances made Don Krieg starve and made that arc about stavation on purpose.
Thematically Don Krieg has nothing to do with hunger or stavation, he's a captain of a large fleet. he's a piece of shit, he's literally called Foul-play Krieg, he's deceptive and cunning, uses cheap tricks and weapons and relies on his armor, that's the character's themes. If he was known to starve his subordinates ocasionally as a form of punishment sure, but that still doesn't change the fact, Sanji has no connection to Don Krieg like i said, he just happen to appear in the Baratie, there's no history.
You're confusing the arc themes with character themes. Wano has themes of identity, doesn't mean Kaido has that theme.
You don't understand this, because it never happens, only that mod guy thinks villains needs to be thematically tied to the candidate, no "Carrot fan" as ever used that as evidence for anything related to Carrot lol.
The only "mold" every SH fits is the role/dream. Everythign else is guesswork
