How does he do only bad things, though? If anything, it's almost a plot hole how goodie two shoes he is.
He is part of the group that captures the early big bad, and interrogates him, then when things go south, takes a bullet for the main character.
Then, as a director of the CIA he finds himself in Wakanda sitting on tons of vibranium, and he...never once tries to radio home to the United States to say "yo, they have tons of Vibranium, we should overthrow their government and take it." Then he decides that he should start feeding American intel to the main characters to help stop the bad guy.
Like, it's weird to me that he doesn't do anything bad; I was suspicious of him the whole movie, but he kept acting selfless and not being a spy.
He also almost sacrifices his life again at the end of the movie to keep the vibranium weapons from leaving Wakanda. ---
