Red Dwarf, Series V

Inquisitor Kryten:
Well, Kryten? Justify yourself.

Kryten:
I'm not sure I can.

Inquisitor Kryten:
But surely your life is replete with good works? There can be few individuals who have lived a more selfless life.

Kryten:
But I am programmed to live unselfishly. And therefore, any good works I do come not out of fine motives, but as a result of a series of binary commands I am compelled to obey.

Inquisitor Kryten:
Well, then, how can any mechanical justify himself?

Kryten:
Perhaps only if he attempted to break his programming and conduct his life according to a set of values he arrived at independently.

Inquisitor Kryten:
Your argument invites deletion.

Kryten:
The rules are yours, not mine.

Inquisitor Kryten:
Do you wish to be erased?

Kryten:
I am programmed not to wish for anything. I serve.

Inquisitor Kryten:
In a human, this type of behaviour could be considered "stubborn".

Kryten:
But I am not human. And neither are you. And it is not our place to judge them. I wonder why you do.
