Yeah but at what point does it become wrong? Is it wrong when someone conceives the idea, when the idea gestates, when the idea becomes full fledged, or when the idea is under way? What if the astronaut just goes part of the way, and we blow up the ship with a remote detonator?

Srsly people who feel the need to project their own life/death values onto others vicariously are one of the major groups we need to eliminate from this planet if we are to move forward with scientific exploration and William Cooper's "star seed."

Maybe they should be the ones we send, they're bodysnatchers/aliens to begin with, send them home.
