"Corporations are not, in and of themselves, evil,"
In practive, most of the Big Ones are evil, in that seeking to maximize their profits, they use their power to suck privileges, tax breaks, subsidies to themselves.
oil/coal/gas are wonderful examples of how corporate power blocks progress to a lower-carbon economy, while polluting air/land/water.
BigFood is evil because it produces industrial food-like substances that are pathogenic.
BigPharma is evil because it produces drugs that maim and kill 1000s as a cost of doing business, because it perverts drugs approval studies by doing its own studies and hiding negative results, because it perverts FDA and doctors with $$$.
etc, etc.
In theory, corporations searching to maximize their profits no matter what the costs are to people, environment, and country is inherently evil. And we're living that evil now.
