Hydra (HYDRA was organized by Johann Schmidt after becoming the Red Skull. It was the Nazi-German Military’s deep science division) is one the most recurring antagonistic characters in the Marvel Cinematic Universe. It first made its appearance in Captain America: The First Avenger (You can watch the trailer of the movie here- ). Cap managed to stop it by freezing himself at the end but was it actually worth it?
In Captain America: The Winter Soldier (You can watch the trailer of the movie here- ), after Cap returns from his long nap, we see him face HYDRA again. They multiplied over the decades and they were there to take over the world again. At the end, they were stopped but all this hassle could have been stopped if Peggy Carter had made a better decision.
In the book The Wakanda Files: A Technological Exploration of the Avengers and Beyond by Troy Benjamin, we see all the notes and annotations by Shuri who has been researching about the past to build a better future. In this we see the history of how SSR (Strategic Scientific Reserve) was transferred to S.H.I.E.L.D and Peggy Carter handled the organisation’s end.
In that we see how Peggy closed off the files about HYDRA without any more investigation stating that the organisation was dead. If it weren’t for her statement, S.H.I.E.L.D would have kept a closer look and many lives need not have been lost.
It has also been speculated that when Cap travelled back in time to live off his life with Peggy, he might have warned her about the future and they together might have stopped HYDRA at the start itself as it was the reason for Bucky’s death. This would have started an alternate timeline as well!
