Depends what you class as people. Is a sentient robot a person? Many philosophers have made the case it could be, and the definition there for person in that field is often not 'human' as much as 'anything with sentience/sapience/whatever'. So may it'd depend how smart the killer robot is and how capable they are of holding a conversation as well as attacking things.
