Yeah, but in Black Panther, the morally/politically correct person is the villain, so there’s that.
EDIT: Maybe not “politically correct” as the term is popularly viewed, and maybe not entirely morally correct since he kills some people, but still, Killmonger was right.
That’s why Black Panther is great. T’Challa’s worldview is challenged and he ultimately takes Kilmonger’s message to heart… so yeah he was right, but Kilmonger was also a murderer trying to commit mass murder, so I don’t think one can really say he was “maybe” morally wrong…
