I think this conversation is going over your head. The writers CHOSE to write Fishbourne's character as being beyond saving and having every organ failing. This isn't about whether characters were racist, but why would a writer choose to make the only black character in the movie that sick and put him on a spaceship with so much responsilibility yet be beyond saving? Also, this movie falls within the classic magical negro trope, where a black character isn't given any in-depth characterization and just magically shows up to help the white protagonists survive, oh and he also dies and disappears just like the classic magical negro as well. This has been done before, and it's most certainly racist as hell.
