Why didn't the T-1000 kill Sarah?

In the factory at the end, when the T-1000 pins Sarah to the wall with his needle/finger and tells her "Call to John", why doesn't he just kill her immediately and call John himself (as Sarah)? We saw him do this with John's foster mother earlier in the film. And it's already been established that any subject that he copies is terminated, so there's no point for him to talk to her at all.

Cameron set up the T-1000's rules earlier on (with John's foster parents), so I don't understand why he slipped up here.

Good point actually, there was no need for the T-1000 to force Sarah to call for John.

Maybe it was because the T-1000 realized that terminating and copying her would not be successful, because of his failed attempt with John's foster parents.

Ther is one error in your point; the Arnold never tells john that the subject is "terminated" for sure. He uses the word "typically." Meaning, killing is not always the outcome.

Perhaps he decided against it because of his malfunctioning, but then did so later anyway when Sarah refused to call John.

Perhaps the T-1000 thought that "death by leukaemia" would be a better way to go ...

His opinion wouldn't be widely shared..

Well it IS the bad guy ...

Haha fair enough.

T3 made a meal of every plot thread.

true

Made a meal of it, fried it and ate it for breakfast.

😂

That part always annoyed me

The novel said that the T-1000's vocals had been damaged by the nitrogen bath. It is possible that it put the Terminator's foiling the attempt with the foster parents down to John's astuteness. Others have suggested that it had some malevolence, so wished for Sarah to be the one to betray her son.

Those are very possible reasons, although it never bothered me too much.

I dont believe the T-1000 had emotions
