Lestat: It's so easy you almost feel sorry for them. You'll get used to killing. Just forget about that mortal coil. You'll become accustomed to it, all too quickly.
Lestat: Claudia. You've been a very, very naughty little girl.
Lestat: For you, Louis. You can pretend it's wine.
Lestat: Oh Louis, Louis. Still whining, Louis. Have you heard enough? I've had to listen to that for centuries.
Louis: They know about us. They watch us dine on empty plates and drink from empty glasses.
Louis: Then out of curiosity, boredom, who knows what, I left the old world and came back to my America. And there, a mechanical wonder allowed me to see the sun rise for the first time in two hundred years. And what sunrises, seen as the human eye could never see them: silver at first, then, as the years progressed, in tones of purple, red, and my long lost blue.
Claudia: I came to make peace with you, even though you are the father of lies.
Lestat: Should we put out the light? And then put out the light. But once put out thy light, I cannot give it vital breath again. It needs must wither.
Lestat: Enough! Enough! Stop.
Claudia: I want some more.
Santiago: But hark, methinks a mortal doth approach.
Lestat: We are predators, whose all-seeing eyes were meant to give them detachment.
Louis: Blood, I was to find, was a necessity as well. I woke the next evening with a hunger I had never felt.
Louis: I'm flesh and blood, but not human. I haven't been human for two hundred years.
Claudia: It's time we were on our way. I'm hungry, and the city awaits.
Lestat: I am afraid, madam, my days are sacrosanct.
Claudia: Who will take care of me, my love, my dark angel, when you are gone?
Louis: Vampires pretending to be humans, pretending to be vampires.
Claudia: How avant-garde.





Answer: It's a matter of technicality. Killing one's own, as in committing murder, would be a different scenario than executing someone for a crime. That seems to be the case here.
