The Driller Killer is a walking contradiction, in the sense that many of his character traits are completely at odds with one another. Though extremely disorganized, both as a killer and in his living space, he is shown to be ruthlessly adept at what he does, apparently living solely to terrify, torture and kill, for no discernible reason or motive. He has devoted his entire being to this cause by occupying and living in the filth and darkness of a factory miles away from most of civilization, waiting for unfortunate passerby to capture and murder. In spite of his blunt and seemingly ham-fisted way of assailing victims by rushing them head-on, he shows a high level of competency in preparation of these attacks.
