"Forget this," you say over your comm uniit, "These are sentient. We can't kill them. It violates interstallar law. I'm calling this mission off." With that, you turn off your comm and return to the ship. Only the captain is there when you arrive; the others haven't returned yet.
"You're calling off the mission?" she bellows as she approaches and strikes you across the face. "This is my mission, scumbag." Now she's pulled a firearm on you.
"You can't do this," you say, "please..."
"Why?" she asks, "it violates interstellar law?"
"Y...yes," you stammer.
"Not if it's self-defense; you came up here ranting about the mission and started attacking me. I had to put you down."
"Wait!" you shout, but she doesn't wait; she fires her plasma blaster right through your heart.
