Serial killers do have conscience. It isnāt that they lack conscience. It is that their consciences lack some of the capabilities that an ordinary personās conscience. The serial killerās conscience does exist, as is evidenced by his ability to self-regulateāand indeed to self-regulate quite as well, at least in most contexts, as the next person.
But the serial killerās conscience is not morally articulated; it lacks, at most, the ability to impose moral strictures on the serial killerās thought and conduct. But even this it does not entirely lack, given that serial killers are, in certain respects, not entirely without morality.
