Today we have two quotes from inventors that are as grisly and depressing as their inventions:

My machine will take off a head in a twinkling and the victim will feel nothing but a refreshing coolness. We cannot make too much haste, gentlemen, to allow the nation to enjoy this advantage.
- Joseph-Ignace Guillotin, inventor of the Guillotine

No, it will make war impossible.
- Hiram Maxim, inventor of the machine gun, in response to the question “Will this gun not make war more terrible?”
