Aloha,
As a long time comic book collector, when I heard of the Cap as Hydra idea, the first thing that came to my mind was this. Steve Rogers volunteered for an experiment conducted by a German scientist who defected. What if the scientist never really did defect? What if along with the super soldier serum, he also gave Steve a dose of something else(hydra brainwashing? Nothing that Steve Rogers has done in his 75 years has been destroyed by this revelation. He must have been a sleeper agent and only now AFTER the return of his youth, has the programming showed itself. As a former stock holder in Marvel comics, I NEVER thought that my being a stock holder gave me any influence on any comic book. The level of entitlement of some fans is amazing.It also makes some look like complete tools because we should know after reading comics for years if not decades that Marvel is not going to destroy one of thier most succesful charcters.
