HYDRA

Dr. Arnim Zola: Accessing archive. 

[Zola shows them old footage of the Red Skull and the original S.H.I.E.L.D founders] 

HYDRA was founded on the belief that humanity could not be trusted with its own freedom. 

What we did not realize was that if you try to take that freedom, they resist. The war taught us much. 

Humanity needed to surrender its freedom willingly. 

After the war, S.H.I.E.L.D was founded and I was recruited. 

The new HYDRA grew. A beautiful parasite inside S.H.I.E.L.D. 

For seventy years, HYDRA has been secretly feeding crisis, reaping war. 

And when history did not cooperate, history was changed.

Natasha Romanoff: That's impossible, S.H.I.E.L.D would have stopped you.

Dr. Arnim Zola: Accidents will happen. 

[Zola shows them HYDRA had killed Howard and Maria Stark making it look like a car accident, along with the recent death of Fury] 

HYDRA created a world so chaotic that humanity is finally ready to sacrifice its freedom to gain its security. 

Once the purification process is complete, HYDRA's new world order will arise. 

We won, Captain. 

Your death amounts to the same as your Life; a zero sum. "
