ANH: Have her fed to the Dianoga.
From Create Your Own Story
You kick her to the floor and gesture for your stormtrooper guards.
"Take her to the trash compactor..." You command. "I've had my fun, let the Dianoga have theirs..." They grab her arms and drag her across the floor, her weak attempts to scream music to your ears. You wish you could go and watch but you don't want to spoil this feeling. The Dianoga that lives in the Death Star's waste system is a tentecled predator of most disgusting habits. The guards will toss her up to her waist in sewage and then she will be mercilessly raped and then eaten by the monster, a perfect finale for your most hated annoyance. You feel Vader standing very close behind you. No doubt he's not thrilled with your choice.
"Sir, do not dispose of the Princess just yet...there is still much use for her!"
"I don't see that Lord Vader, she has served her purpose just fine. And just like a rations tray I do what I do with that when I'm finished with it...I throw it in the trash..."
"The Emperor will not be pleased when he finds out what you've wasted Tarkin..." he rumbles angrily.
You raise an eyebrow. "You plan to tell him?"
"The Emperor will hear everything he needs to know."
You shrug and leave the viewing chamber, ignoring Vader. "Do what you must, but be mindful Vader you still curry less favor in the eyes of our Emperor than I do. I have my wiles as well..."
Bothersome cyborg, you mutter. No matter, this has been a good day.
