Heretic of The Seventh Circle
If your only path forward is “gun to a child’s head” I’m not going to engage further.It might be worse, but primarily because I don't think prison guards could be trusted not to abuse such power.
Take a different example. A violent criminal has a gun to a child's head. There is no question in anyone's mind that the criminal will shoot the child unless stopped. You have only two guaranteed ways to stop him. You have a sniper who never misses a head shot. And you have a telepath whose niche superpowers allow them to force violent criminals to surrender to the authorities peacefully. Or you can choose a third option, but the child's survival is not guaranteed. Which do you choose?
Personally, I think using the telepath is the obvious moral choice.
