The guillotine was the first attempt at democratic execution.
Prior to its invention, if you were poor you would languish for days under all sorts of bizarre tortures until you were finally drawn and quartered. If you were rich you got beheaded (a relatively better exit)
Dr Guillotine invention was proposed so that all would be executed in the same quick manner, rich and poor. I do not think he ever imagined the assembly line use of it in the French revolution.
Today of course things are much better, if you are poor you get executed and if you are rich and can afford the legal team you get life (or even acquittal...!)
Plus ca change, plus c'est la meme chose.
