"Did you ever, at any time, second-guess yourself and question whether or not you actually wanted to fight for HYDRA while they were using you?"
It was once Steve came into the picture, I began to realize what am I fighting for? However my programming was stronger than I was (at the time), so I continued to follow out orders up until the point where I saved him.
Now I'm program free (I'm pretty sure) and I regret what I did (or at least what I can remember).
