M: Did you hear on the news today about that ... uh ... murderer who was executed?
W: I can’t believe it.
M: Yeah. That’s the first time in ten years that they’ve used capital punishment.
W: I just can’t believe in our society today that they would actually kill another human being. Nobody has the right to take another person’s life.
M: Oh, I don’t agree. Listen, I think capital punishment is- it’s about time it came back. I think that’s exactly what killers deserve.
W: No, they don’t deserve that. Because once you’re killing a killer, you’re the killer, too. You become a killer as well.
M: No, listen. You take a life, you have to be willing to give up your own. And also, I think that if you have a death penalty it will prevent other people from killing. I think it’s a good deterrent.
W: I don’t think it’s a good deterrent at all. My goodness gracious. I mean, first of all, are you sure the person you’ve convicted to death is really guilty?
M: Well, I think that’s a very rare ... very rare incidence.
W: I don’t think it’s rare, with all the cracker jack lawyers we have today, and the judicial system the way it is.
M: I think it’s a rare incidence, and I think it’s more important to get rid of the ... the bad seed, you know?
W: But you don’t get rid of it. You rehabilitate somebody like that. You don’t eliminate, you rehabilitate.
