Most corporations are set up such that their primary responsibility is to increase shareholder value, by their very nature they "must" behave like this by design, nothing else matters as much as shareholder value.
I sometimes think of these corporations as the first gen offspring of humanity, the first autonomous "intelligences" that are designed more or less to be giant predatory behemoths if they succeed in their objectives. They're even granted many of the rights of personhood in a lot of the world.
