Eichmann was a Kantian

“If a man believes that the good is intrinsic in certain actions, he will not hesitate to force others to perform them. If he believes that the human benefit or injury caused by such actions is of no significance, he will regard a sea of blood as of no significance. If he believes that the beneficiaries of such actions are irrelevant (or interchangeable), he will regard wholesale slaughter as his moral duty in the service of a “higher” good. It is the intrinsic theory of values that produces a Robespierre, a Lenin, a Stalin, or a Hitler. It is not an accident that Eichmann was a Kantian.”
