Murder, She Wrote1984

Woman:
I don't understand how you could do it. I mean you said yourself he was your friend. The guy he murdered was probably a killer several times over, a lot worse than your friend. So why do it?

Jessica Fletcher:
Yes, well uh, it was, it, it was the hardest thing that I've ever done. But, popular culture not withstanding there is such a thing as right and wrong. The taking of a human life for any reason is wrong. You can never nudge the moral compass far from its true North without losing something vital. A compass is essential for everyone, writers in particular. Yuri Malenkovich asked why I investigate murders. He said that I had to have a personal agenda. Well he was quite right. It's important to me to pursue those who cross the line, and take another human life. In my investigating murders, I've seen some terrible things. So many of them it would take the wind out of anybody's sails.
