Good point. This also explains why we are so willing to delegate "killing" to external entities, such as job occupations (when the "killing" involves chickens and cattle) and authorities (when we target war enemies, terrorists and the like. Of course this comes with very strict safeguards and due processes.) More recently, we have also started delegating our "killing" to machines such as drones; admittedly, this ignores the truism that drones don't kill people, people kill people.

Maybe if we were less deontological and more consequentialist in our outlook, there would be less of this kind of delegation.
