Invisible men

About a week before I read this my roommate and I watched the 1933 horror movie The Invisible Man. The movie was a dark look into the madness that took over a scientist who created a way to become invisible via experiments. Comparing the two stories: in the movie the invisible man murdered and caused mayhem among a town because he could and felt superior to the townspeople. He did want to find a cure initially, but realized this new found power was too good to resist.
