Evil implies that corporations can be judged as humans, but they are not : corporations are just soulless. They knows neither right nor wrong. By definition, a corporation exists merely as a maximization function toward the goals of its shareholders. That is why, in spite of having legal personality, corporations cannot exist in the political sphere that holds control and oversight in the name of the public good – though the extent to which the financial resources of corporations are employed to influence political campaigns shows how poorly that separation of power is applied.
Charles Stross’ Accelerando is heavily loaded with buzzwords – though it is a fun read and a great reflection on post-humanity. Among the interesting concepts that pepper the story, I found the “Turing-complete company constitution” – if you have legal personality, then why not Turing completeness ? And then why not go all the way to human-equivalent sentience and cognitive abilities or better ? You may, but it won’t matter because whatever their sophistication, corporations have a mandate inscribed in their lowest level code that merely makes them paperclip maximizers.
Whether you consider them anthropomorphic artificial intelligences or just really powerful optimization processes, corporations don’t care about you anyway. To paraphrase Eliezer Yudkowsky : they don’t hate you, nor do they love you – you just happen to be resources that they can use for something else.
