Bucky understood tools are amoral:

"The military also buys soap and water, but

that doesn’t mean soap and water must be boycotted

by those who hate war. They also buy pencils, and

it’s perfectly clear to me that a man could use a

pencil as a dagger or he could write a prescription to

save a child’s life. So how tools are used is not the

responsibility of the inventor."
