While these employees were certainly committing fraud and knew better I think it's an enormous stretch to call Wells Fargo a victim. At this point in human cultural development we have a solid grasp on the power and danger of perverse incentives. Particularly in safety and finance.

There's no excuse for a financial institution to not have policies and processes to prohibit, prevent and detect misaligned incentives put in place by sales organizations/departments/teams within the institution. No one wants to mess with their sales organizations without being legally compelled to since they're the ones generating income but financial institutions have a special responsibility and obligation to society to not fuck things like this up.
