Chris to Keller: "I want to know when you did, now what did you do? You had a hundred and twenty craked engine-heads, now what did you do?". How does Keller try to justify his actions and how does Chris react to the confession?

Chris turns to Keller, finally understanding. Keller does not deny it; he ordered those cracked cylinder heads to be shipped out. Yet, they did not go into the type of plane that Larry flew. Chris says that Keller killed twenty-one men, and Chris then calls him a murderer. Keller explains that it was a matter of business: you work forty years, and in one moment, one failed shipment, the contracts can be torn up and you can lose everything. He thought that the military would notice the cracks anyway and that if they did not, he would warn them. But it was too late--the news was all over the papers that the planes had crashed, and the police were knocking on the door.

Chris is flabbergasted that his father suspected the planes would crash. Furious and betrayed, he asks why his father would do such a thing. For him, his father replies--for Chris, for the family, for the business. Enraged, Chris rants about his father's small-mindedness, in particular his lack of empathy with his countrymen and the human race. "No animal kills his own, what are you? What must I do to you?" He stumbles away, weeping, as his broken father cries out to him.
