"Forced to." Steve said in a quiet tone, unable to argue against anything else Tony said. It was true, Bucky was the one that killed Maria and Howard Stark, even if it wasn't his fault. Even if he didn't want it, the fact remained that it happened. HYDRA was the one responsible in the end, but it was impossible to deny that Bucky played a role in it, even if it was unwilling. "I'm just as responsible for that incident as he is. Maybe more."

Because he couldn't save Bucky. Couldn't get rid of HYDRA completely. That laid on his shoulders and his alone.

"Clean." Steve winced for a moment at his wording. Fury wasn't clean, not by a long shot, but he wasn't HYDRA. "He noticed HYDRA growing in SHIELD, tried to take them down."
