The Asset is really happy with Hydra, it feels accomplished when a mission goes well. It doesn't really remember what normal food is like, but it is happy with what Hydra feeds it. It's handlers are the best, they are really efficient and know how to properly use The Asset. They even let the Asset come sometimes.

Basically, I want the winter soldier so completely brainwashed that he loves all the horrible things Hydra does to him and believes everything they tell him. He's happy but only because he doesn't know better.
