But, there is that line from "Dead Man Walking" where Penn's character indicates that, despite the calm expression on his face, he will still feel enormous pain as his heart is stopped by the killing drug. So, I don't know that there is an actual "humane" way to do it if "humane" in this context means pain-free.
That's what I'm asking. In both the case of my colonoscopy and my kidney stone stuff, I had zero awareness and was fully sedated. They could've thrown me off a building, blown me up, whatever. I just don't get how there could be pain -- I was unconscious.
It seems like a 3 step process would make this super easy:
- sedative/relaxant
- make them unconscious
- lethal dosage
