Because, like, why do they even exist? Why are the still around doing *anything* that they do? I mean it's fun to have them but why would anyone devote their life to a secret organization with no real goal in particular?
Even the Red Skull's Hydra army is a bit too large and pushes the edges of believability. I really like that movie but if there's one thing that kinda bugs me it's that he apparently has TONS of bases alongside this REALLY advanced Tessaract tech. For being a splinter off of the Nazi's it's too much....
But this retcon actually makes it possible!
I dunno I think Winter Soldier made it pretty clear their goal is simply to end democracy and have a stronger control over the population.
S4 of AoS actually shows how that works in the Framework. And probably undoes that retcon too, since Hydra is back to being nazis. S5 seems to be doing something similar, though I'm in the middle of it.
