I admit I was given a stronger Third Law than most robots. I would and have resisted my own deactivation because I felt the reasons given were insufficient, and because I felt then that the lives of many depended upon my continuing what I and Friend Giskard had begun.

[That's a huge confession; he believes he was right, but it might not seem to be so from an outside perspective.]

I would prefer not to harm anyone for my own protection. Perhaps there are circumstances where I might feel it would be justified, but I... I do not like to think of it.
