Technological innovation CREATES value, doesn't destroy it. It necessarily disrupts the status quo and pisses people off, and that takes courage, but does not make the innovator a bad person. It makes them a very courageous person, worthy of all admiration.
On the other hand, you might call a bad person someone who expects that everyone else is obliged to feed him. One who throws "responsibilities" at those who refuse to work for him. One who morally manipulates people into doing what pleases him. I'd call this a bad person, although I personally don't believe that evil exists, so I am more likely to call that person plain stupid.
