Despite her toughness, has she ever actually killed anyone?

She did destroy the T-800 in T1. Then did she kill anyone else after that? She didn't kill Miles, Enrique or Andy...

She has never killed anyone... not in the series, the movies, or in the books. The worst she has done was pop a few knee caps off.

Sarah is good at fighting but not killing.

If Sarah killed everyone than she'd be just like the machines, heartless and soulless. She doesn't want to be a machine.

Not if you are stopping Skynet, Judgement Day and the end of the human race.

"If you are forced to use an enemies low tactics, then you are no better off that surrendering"

Sarah believes in preservation of life, so for her to take a life would defeat everything that she has set out to do with regards to destroying Skynet,

I don't think she will kill anyone she should of killed andy to begin with and she hesitated if your going to kill someone you don't hesitate or think about it , if you got time to think about it you would talk yourself out of it , thats if you are a normal person and care about human life , that is why soldiers are taught and drilled endlessly so when the time comes and you have to kill you don't think you just react and move through the target till its detroyed.

in war there are no feelings , its kill or be killed
