One person doesn't do this, a company does, a hierarchy of jobs. An entity without a conscience built from entities with a conscience. Very clever.
So there's not much difference is there?
Actually there is. The difference is in a quirk of moral evolutionary psychology. The tragedy of the commons. As an individual each of those entities contributes negligible evil to society. In aggregate that negligible evil becomes prominent.
Morality is divided up into fractional shares and sold like a collateral debt obligation. Every time you step into a car and let that thing spew green house gases into the air you are contributing to the destruction of the world. The individual is still guilty. We call corporations evil, but what we don't realize is that corporations are a mirror of humanity.
