Amoral is the word you're looking for and Joel Bakan is clearly mistaken -- corporations are tabula rasa with a single directive, "grow" they then go on to embody the qualities of the leadership and the regulatory climate under which they exist.
It's up to the government and the people to limit their scope, or not if they choose. The mistake America made was legalizing corporate lobbying of the government which enabled regulatory capture, but that is an old mistake and there is no real will to change that other than the normal handwaving and guffawing.
