Which Death Did Marvel Producer Try To Stop?

In 'Avengers: Infinity War', several of Marvel's best heroes die at the hands of Thanos.
Black Panther producer Nate Moore reveals he personally asked the film's directors to reconsider one death.
Moore did not want to see Black Panther die.
He said seeing Black Panther die was hard, but for the sake of the story it "made sense."
--I love that we got to see a little bit more of Wakanda in that film, and I hope to see how they’re going to resolve that.
