If you’ve read Asimov you’d know that the rules were meaningless in the end, the whole point of the story was to show how no matter what you can bend and circumvent them. A robot can be programmed to never WILLINGLY break the laws, but you can always trick them into doing so without realizing it.
Human: Robot, go kill this guy
Robot: I can’t its against my programming
Human: Put rat poison in bowl
Robot: Ok
Human: Put soup in bowl
Robot: Ok
Human: Serve bowl to this guy
Robot: Ok
