Sorry, I don't think the old "but they were just making money for shareholders" argument is gonna fly considering the financial catastrophe of 2008. Everyone who had a finger in the subprime pie knew what they were doing was extremely risky, and when it all fell apart, their buddies in Washington were quick with the cash. Sure, they may have paid it back, but that doesn't excuse the systemic failure of the financial system and its regulatory structure (I heard the running joke on The Hill is that the Treasury Dept is just another branch of Goldman).
I doubt those people even think they did anything wrong...
