So, you don’t consider putting a stop to evil a good?
I can think of a vew other good uses. Kicking an interplanetary craft out of the Moon’s orbit on its way to Mars might be good. Sealing off a volcano might be good. Kicking LA into the ocean would definitely be good.
Oops, did I say that last one out loud?
"Putting a stop to evil" is not the specific, guaranteed outcome of a nuclear detonation in a war situation. Killing people and destroying stuff is the specific outcome - just as it is for a conventional detonation - and those are objectively bad outcomes. That's why I said "Evil that deters greater evil."
A nuclear detonation as a propellant in space wouldn't really be a "nuclear bomb," but a thruster. Using one on a volcano would be stupid, imo.
There are some nice people in Los Angeles.
