Bucky , the Winter Soldier, has some, uhhm, trouble with mind control, to the point that he don't trust himself that much.
Nick Fury behaviour had always been shady, but he ha dbecome oddly erratic and shadier prior his disappearences, also he is a man with thousand of secrets. And yet he see nothing when the "Secret Bomb" go off.
He acted as advisor to bucky when he tried to return to normal life, even if they were not that close before.
M theory is that Nick didn't rely just on LMD, or not just the old mechanical LMD(seen last time he faked his death). Also he has sued lot of LMD just to run his day by day job at times. Why?
Now look at the guy in shadow who pull the strings. He is very nick fury like in behaviour, but with more odler look, hair expecially give a much less youthful vibe.
So is possible that the infinity serum that granted him longevity had stopped to work some times ago(not necessary too much time ago) and had used advanced LMD as well as Brainwashed friends(not limited to Bucky...remeber the secret war to Latveria?) to do the job he felt needed to be done but couldn't do anymore in first person.
Infact Nick Fury recent exploits had always been about fixing some mistakes of his past or something he had overlooked for too long.
And now he had decided to deal with the cosmic entities who had manipulated way too much humankind's fate (Uatu is the ultimate quantistic observer. He don't need to be visible at all, and yet he ALWAYS make himself visible. WHY?!? It automatically alter the events he is observing!).
Is possible that Bucky had realized this in flashback and see that HE was used as killer by one of his supposed friend. his reaction could be understandable if not justifiable.
....
But this si just my silly premature theory that has great chance to be so wrong that more wrong couldn't be.
