If they want to live, I have no problem with it. I am not advocating killing them. I realize this is my personal preference. Feel better now?

I don't know what kind of disclaimer I would even add. "Don't become a serial killer because I said this?"

And I question whether it really is uncommon for people to choose death over severe disability. Why do so many people have living wills?

I don't think this is dangerous. What's dangerous is if the person doesn't realize that not everyone shares their personal preference.
