PLEASE HELP How, and with what methods, does this exctract become such a powerful moment in the play?

Play: All my sons - Arthur Miller

Mother: Altogether! (To Chris, but not facing them) Your brother's alive, darling, because if he's dead, your father killed him. Do you understand me now? As long as you live, that boy is alive. God does not let a son be killed by his father. Now you see, don't you? Now you see. (Beyond control, she hurries up and into the house)

Keller: (Chris has not moved. He speaks insinuatingly, questioningly) She's out of her mind.

Chris: (in a broken whisper) Then... you did it?

Keller: (with the beginning of plea in his voice) He never flew a P‐40...

Chris: (struck. Deadly) But the others.

Keller: (insistently) She's out of her mind. (he takes a step toward Chris, pleadingly.)

Chris: (unyielding) Dad... you did it?

Keller: He never flew a P‐40, what's the matter with you?

Chris: (still asking, and saying) Then you did it. To the others.

Both hold their voices down.

Keller: (afraid of him, his deadly insistence) What's the matter with you? What the hell is the matter with you?

Chris: (quietly, incredibly) How could you do that? how?

Keller: What's the matter with you!

Chris: Dad... Dad, you killed twenty one men!

Keller: What, killed

Chris: You killed them, you murdered them.

Keller: (as though throwing his whole nature open before Chris) how could I kill anybody?

Chris: Dad! Dad!

Keller: (trying to hush him) I didn't kill anybody!

Chris: then explain it to me. What did you do? Explain it to me or I'll tear you to pieces!

Keller: (horrified at his overwhelming fury) Don't, Chris, don't...

Chris: I want to know what you did, now what did you do? You had a hundred and twenty cracked engine heads, how what did you do?

Keller: If you're going to hang me then I...

Chris: I'm listening. God almighty, I'm listening!

Keller: (their movements are those of subtle pursuit and escape. Keller keeps a step out of

Chris's range as he talks: You're a boy, what could I do! I'm in business, a man is in business. A hundred and twenty cracked, you're out of business. You got a process, the process don't work you're out of business. You don't know how to operate, your stuff is no good, they close you up, they tear up your contracts. What the hell's it to them? You lay forty years into a business and they knock you out in five minutes, what

could I do, let them take forty years, let them take my life away? (his voice cracking) I never though they'd install them. I swear to Got. I thought they'd stop 'em before anybody took off.

Chris: Then why'd you ship them out?

Keller: By the time they could spot them I thought I'd have the process going again, and I could show them they needed me and they'd let it go by. But weeks passed and I got no kick‐back, so I was going to

tell them.

Chris: Then why didn't you tell them?

Keller: it was too late. The paper, it was all over the front page, twenty one went down, it was too late. They came with handcuffs into the shop, what could I do? (He sits on bench) Chris... Chris, I did it for you, it was a chance and I took it for you. I'm sixty one years old, when would I have another chance to make something for you? Sixty one years old you don't get another chance, do ya?

Chris: You even knew that they wouldn't hold up in the air.

Keller: I didn't say that.

Chris: But you were going to warn them not to use them

Keller: But that doesn't mean...

Chris: It means you knew they'd crash.

Keller: It don't mean that.

Chris: Then you thought they'd crash.

Keller: I was afraid maybe...

Chris: You were afraid maybe! God in heaven, what kind of a man are you? Kids were hanging in the air by those heads. You knew that!

Keller: For you, a business for you!

Chris: (with burning fury) For me! Where do you live, where have you come from? For me! ...I was dying every day and you were killing my boys and you did it for me? What the hell do you think I was thinking of, the Goddam business? Is that as far as your mind can see, the business? What is that, the world of business? What the hell do you mean, you did it for me? Don't you have a country? Don't you live in the world? What the hell are you? You're not even an animal, no animal kills his own, what are you? What must I do to you? I ought to tear the tongue out of your mouth, what must I do? (With his fist he pounds down upon his father's shoulder. He stumbles away, covering his face as he weeps) What must I do, Jesus God, what must I do?
