Corporations should be assumed to act in line with their interests, which is the bottom line. "Morality" isn't the lens that you need to try to view them through to understand their intentions and actions. But yes, their motivations pretty much always lay outside of any moral good due to the nature of them.

And yet, pro-social behavior has evolved many times independently through natural selection.
