“I believe, Jack, there are two kinds of people in the world. Killers and diers. Most of us are diers. We don't have the dispoisiton, the rage or whatever it takes to be a killer. We le death happen. We lie down and die. But think what it's like to be a killer. Think how exciting it is, in theory, to kill a person in direct confrontation. If he dies, you cannot. To kill him is to gain life-credit. The more people you kill, the more credit you store up. It explains any number of massacres, wars, executions. […] In theory, violence is a form of rebirth. The dier passively succumbs. The killer lives on. What a marvelous equation. - Murray (WN 290)”

“Nothingness is staring you in the face. Utter and permanent oblivion. You will cease to be. To be, Jack. The dier accepts this and dies. The killer, in theory, attempts to defeat his own death by killing others. He buys time, he buys life. - Murray (WN 291)”

“You're a stone cold killer, Frank. You kill people for a living. And so does this German guy. You aren't heroes. You're what most people fear. You're the antitheses of a hero. You ever think of that?”

“There are two kinds of people who sit around all day thinking about killing people...mystery writers and serial killers. I'm the kind that pays better.”

“Because this devil is definitely an older man, probably foreign. The FBI would classify him as a type IV killer, the worst kind and difficult to catch. A type IV serial killer has no remorse, doesn’t understand the concept. He has what they call an anger-excitation profile. The whole process he performs is his own way to sexual gratification. This man kills for sport. He’s not out of control, quite the opposite in fact. Most importantly, in regard to your daughter’s safety, the rules of his game are that he must murder strangers. He doesn’t kill people he knows. So if your daughter’s with people she knows then she cannot be with the killer.”

“People think that it's the beast that makes us lose our sanity. They think the beast takes over and we become loup. Animals don't destroy each other for pure pleasure. They don't have serial killers. They kill, they don't murder. No, it's not the beast in us that makes us lose our balance. It's the man. Of all the animals, we're the most aggressive and the most predatory. We have to be, otherwise we would've never survived. You can see it in children, especially adolescents. Life is hard for them, so they attack it and fight for their own place in it. Homo homini lupus.”
