It seems to me that the title is misleading. When the pilot deploys the missile, it is the pilot who has made the decision to ‘kill’. The missile can then make a decision NOT to kill if it does not find a proper target.
I tend to agree.
This is a missile. It must be launched, and only then does its calculation become something to be concerned with.
I agree we don’t want weapons which sit around and wait for themselves to “calculate” that there is a threat, but a missile does not launch itself.
