I have to say I'm not I would call someone that creates something that doesn't work (and will never work) and inventor.
If I just jump from a building and throw a bottle on the way down, saying that the bottle will 'throw me back up because physics', and then I die (obviously), I'm not an inventor, I'm just an idiot.
Furthermore, in relation to the title of this article, I wouldn't say the invention of his parachute killed him. It was just the force of him hitting the ground once his invention failed to work. ;)
