Ever wondered if Harold had made different choices. Who'd still be alive and who'd be dead? This show is as philosophical as it gets. The choices, the morale & the ethics of a person; inclusive of all it's butterfly effect. The world without ASI's aren't any better or worse, just slightly different. Samaritan would have emerged anyway, as Claypool was already working on it with the NSA. It was Greer who corrupted it. "How arrogant of you to think of us anything but irrelevant." And indeed we're all irrelevant in the end. Ethical dilemma and necessary sacrifices (as in Chess); will it all come down to winning or losing? I remember Harold saying, Grace is all that matters. And the password was eight-lettered. DASHWOOD. The character from Jane Austins, Sense & Sensibility. The same book in which Harold had embedded a ring to propose to Grace. I think she might be play a Key-part in Return 0.
