Scott: What'd you want?
Charlie: I'm trying to figure out how you could kill a man. How you could kill a fellow scientist... to steal his work.
Scott: Is that why you think I killed Dr. Hoke? For money?
Charlie: You weren't jealous of his accomplishments.
Scott: His accomplishments. Is that was you call them? I grew up in West Oakland. Anyone I grew up with, who isn't dead or in prison, is flipping burgers or driving a truck. And it's not too difficult to guess what Dr. Hoke's formula would have said about putting a computer lab up in my high school. That computer lab saved my life. And next year it's going to save somebody else's.
Charlie: And killing Dr. Hoke accomplishes that? You think it stops there?
Scott: Well, in the last century, the Nazis used the theory of eugenics to stop the poor from reproducing. Eventually, they justified just killing the sick ones.
Charlie: You can't compare that to this.
Scott: Actually, that's a perfect comparison, 'cause what Jonas was doing was taking away a person's chance at life. It's taking away someone's hope, and I did what I had to do to stop that before it started.
Charlie: That makes you a murderer.
Scott: Have you ever thought about your own work?
Charlie: ...What about my work?
Scott: Well, you consult for the NSA, don't you?
(Charlie nods slightly.)
Ahh, of course you do. So you gonna tell me that everything you do will be used for good, all the time?
Charlie: What's your point?
Scott: Well, you're asking me how I'm gonna live with myself... look in the mirror. Ask yourself the same question.
