An iron maiden and a wheelchair sit on different places in the good - evil spectrum.
No they don't. They are both just objects, people are the reason the iron maiden has the connotation it dose. The iron maiden could have been a single art piece in a modern art gallery somewhere meant to symbolize the pain of heartbreak. Wheelchairs could have been devices used to intentionally cripple children by preventing them from using their legs.
We need to stop living in this fantasy land where people aren't responsible for their actions. I'm comfortable making the assertion that it is an absolute fact that guns, the internet, and all technology are neutral until applied/activated by a thinking being (AI would count as a thinking being, IMHO). What if no human had ever died from a gunshot? What if we only used them to kill cows for consumption, would guns still be inherently evil (bare with me if your vegan)? Is it not humans who first choose to point guns at eachother?
We can't let personal responsibility die. We just can't... Otherwise all tech may as well be evil. You don't think there is an evil way to use a heart bypass machine? I bet I can find one. Give me any piece of tech and I can find a way to use it for evil, and a way to use it for good.
Even nuclear bombs could be used to save the planet from an out of control asteroid without doing anything evil. Or you could blow up a city of people. Where dose the difference lie? With the person whose fingers on the button.
