Yeah, I think keeping a comatose person alive for years with no hope of a solution is inhumane.
I mean a comatose person who will definitely wake up. Someone who is completely unconscious but will eventually recover. According to your own words, killing that person (not ‘pulling the plug’) while they sleep is not actually murder.
If you think somebody who is knocked out is the same as a mass of cells that don’t even resemble a person are the same then you are a pure and unabashed idiot.
How? That mass of cells will resemble a person in six months. What’s the difference? An infant doesn’t look like an adult. Does that make it not human?
