What makes certain agglomerations of atoms "living beings"? I don't see a fundamental distinction between "alive" and "not alive" that would apply to humans yet would not also apply to larger organizations. Now, the question of whether certain companies should be considered "evil" may not be something I want to spend a lot of time on, but the arbitrary philosophical distinction that only humans within those companies can be "evil" makes the discussion even less interesting.
