Star Trek: Deep Space Nine1993

[Kubus, a former collaborator, has requested that he be allowed to return to Bajor, which Kira denies]

Kubus:
Major! I'm an old man. I don't have many years left. What's the harm of letting me live them out on Bajor?

Major Kira:
When the Cardassians needed a new group of Bajorans to work in the mines, who approved those work orders?

Kubus:
The Bajoran government.

Major Kira:
Whose signature was on those authorization forms?

Kubus:
[after some hesitation] Mine.

Major Kira:
And you had to know that those authorizations were death sentences. Did you ever *once* refuse to sign them?

Kubus:
[shakes his head] No.

Major Kira:
And that's why you can never be allowed to set foot on Bajor again. Because if you do, it would dishonor the memory of every person you sentenced to death.
