Are scientists and engineers responsible to the culture for their discoveries?

“Discovery consists of seeing what everybody has seen and thinking what nobody has thought.” Albert Szent-Gyorgyi, 1937, Nobel Prize Winner
When an inventor creates - whether it is a hammer, a bomb, a computer, or a phone, there is a notion that it will be used. It is their responsibility to ensure that it is of sound quality. Building upon ideas, as many great inventors have done, allows others to create, explore, and learn. It is their responsibility to not only take credit for the item's successes, but also for its failures. (Example: Poorly designed vehicles)

"Technology giveth and technology taketh away" (Postman, 1998, p.2).
Our culture incurs great responsibility with the addition of discoveries and technology. If we use the invention in a way that was not intended by the inventor, then how can we hold the creator responsible? It's like holding God responsible for the evil in the world. People have free-will an will do with it as they please and we cannot hold scientists and engineers responsible for this. (Example: Chat rooms are places where people gather to converse, share ideas, and passions. When cyber-bullying takes place, many young people are so badly affected by these virtual assaults that some resort to suicide. Can we hold responsible the inventor(s) of chat rooms and the internet? No.)
