Ofc Sanji would have died like anybody else. But that scene is beautiful because it show how much sanji cares about zoro. He really admires him and want him to fullfill his dream just as much zoro and the other mugi want luffy to become pirate king.
Also Sanji and Zoro respect each other a lot, and they were much much closer in pre time skip, now its all fights and gags between the two and is sad.
