Fucking horrifying. Imagine looking at your body from a distance as blood pours out of your ruined neck... Final thoughts must be absolutely terrifying. Brain is desperately firing signals down your nerves, but they aren't reaching their intended muscles and such... I'm sure this induces panic and shock. I think it's the swiftness of the beheading that determines how conscious the condemned is. Like if a dude took three chops with an axe to lop your head off, you might start losing consciousness after the second strike. But a guillotine, *instant* separation of the nervous system from the brain.
