The whole is greater than the sum of its parts. - Aristotle
Companies exhibit emergent behavior that might be hard, if at all possible, to predict if you only had a single individual as reference. For instance, most individuals would probably never agree to manufacture a weapon that is specifically requested to kill your neighbor. However, this same individual will show no empathy and remorse for their labor in a company that produces something that is used to commit incredible destruction to the earth, even contributing to the deaths of millions of people.
