No matter how you slice it, it's not possible to equate humans to tools like this. If the SEAL receives an order to stand at attention until told otherwise, he will not stay in place for weeks until starving. An algorithm will work towards its self-destruction if ordered to - it doesn't care, it doesn't have the biological signals telling it otherwise. If the SEAL is lost somewhere with no one to give him orders, he will soon start acting on his own to ensure his survival and comfort. A tool will not do anything until directly activated and used by something that does have an active will, like a human. If the SEAL is ordered to massacre his hometown, no matter how obedient he is, he might have reservations. An algorithm with no instincts to get in the way will do anything if this behavior isn't somehow inhibited by people during training. It wouldn't even need the explicit order, if an irresponsible operator tells it to accomplish something by any means, that means that anything is on the table. Good thing the AI labs aren't stuffed to the brim with irresponsible operators.
