I believe the opposite on this actually. You may be the creator of something, but once you've shown it to me, it becomes the property of the human race. Something our species has done and enjoyed (or hated). You have no right to erase it from existence. You could make a big speech about how bad it was, put a warning at the start, etc, but removing it entirely from existence is just vandalism. Imagine if the Pharaohs decided to blow up the pyramids after they built them!
