Fury is a Skrull, he is trying to weaken Earths defenses.
In Winter Solider he engineered the Hydra takeover of Shield in order to remove Shield and the weapons they were creating with the tesseract. No advanced weapons, no resistance. He knew all along about the Hydra takeover and pushed it forward. He even made it look like he died, an easy giveaway that he is a Skrull. A Skrull can morph into a person with their guts laying out, just for fun even. This ballsy Nick Fury replacement was playing a dangerous game when he let Hydra attack him in his car, but he kept at it, ran his con and in the end both Hydra and Shield were removed from the board. Skrull gets a big win. Two threats wiped out.
He intentionally did not page Captain Marvel during the New York attack because he wanted the Avengers dead and the Earth further weakened. His ideal scenario involved Thanos coming to Earth and the avengers dying trying to kill him. If Thanos dies too, great. Thanos is a problem and the Avengers are a problem. Let them take each other out on Earth.
He never investigated Tony Stark’s parents murders or if he did, he covered it up to use when he felt necessary. If he had looked into it, he would have noticed that a former serviceman who fought beside Captain America named Bucky Barnes looked a lot like the guy who killed Tony starks parents. Why not diffuse the argument by bringing it up before it had a chance to boil over? He might have even been Zemo himself in the civil war movie. Could be the same guy.
He engineered a situation whereby Tony Stark would feel alone, without Shield and isolated from any U.S. government guidance or insight. He never stepped in when Tony was drinking alcohol to talk to him. Didn’t prevent the proliferation of Iron Man armor via War Machine stealing it when by stepping in he could have - all because he is trying to arm lots of factions on earth with machines he knows backdoor hacks to get into. Trying to remove the possibility of a coordinated Iron Man defense against Skrulls makes perfect sense.
You think Nick Fury didn’t know about Wakanda? Come on. He needed to find a way to get this tech giant’s shields down. What’s better than getting them involved in high stakes emotion heavy violence over the death of their king? Bring them out into the world and see what happens. Try to get inside and find out what you can. Learning more about Wakanda is a key for a takeover of Earth.
How do you think the Hulk went from flying in that Shield airplane to just moving off the planet and into an arena tournament on this junkyard world? The Skrull probably had people living in the junkyard. The people who brought hulk might have made good money betting on him and worked their way out of the ghetto. Plus it's the closest thing to killing him, without anyone knowing what happened. On that Arena world with Jeff Goldbulm loving him, giving him a throne and a place to sleep, he should theoretically be both gone forever and right where the Skrull want him to be: where nobody else can find him, training. Alive in case they ever feel they need to shapeshift into one of his friends to convincing him to do something. Fury couldn’t predict Thor would make his way there.
Fury is probably operating as a single agent among a network with the responsibility of weakening planets like Earth in any way possible and preparing it for Skrull invasion/replacement.
Might even work for a more militant branch of Skrull, who would have killed the British Skrull without hesitation. Or perhaps the British Skrull was a red herring and many Skrull still remain.
The duplicitousness of the Skrull must never be underestimated.
Of course when Thanos wiped out half the life in the universe, that was too far for Nicholas “Skrull” Fury because he wiped half the Skrull too. He therefore had to call in Cap Marvel.
Skrull Fury will return
