I can guarantee Schwarzenegger is going to let this one live. The first decision made him look tough, this one will make him look compassionate. He factored this one in when he made the earlier decision.
So he spikes the black prisoner and spares the white prisoner? I don't see that happening.
He could always show his compassion by starving the guy to death. That way the guy will appear more beautiful, die peacefully, die with dignity, and go out in a euphoric state.
Yep. The kindest thing to do is starve the guy to death.
