1) Yes. But keep in mind that "an eye for an eye" was, in the OT, an application meant to keep things under control. It would appear (to some scholars and, from what I gather, myself) that "an eye for an eye" was a plea/command to make punishment be no more severe than the crime committed. You would not, say execute a man for the act of theft, but you would execute him for murder.
2) I did. Now, perhaps I am misunderstanding the mindset or intentions of those who beat the drum of saving the killer's life. But again, in my perception, I see a much greater concern for the murderer than the murdered. I know that I am not alone in this.
Perhaps I have more to say, but dianegcook, above, said it for me and better than I could.
