Jim, it wouldn't matter how many minds you changed. What you are hoping for is that those involved would refuse to help them, thereby taking away their right to choose. And I repeat, THAT is playing God.
And if, down the track, somebody with an intolerable condition / circumstance such as theirs is told by someone like you that they will just have to put up with it because you know what's best for them, That will be WRONG.
By the way, medical professionals are committed to improving quality of life, as well as saving life. The operation was very risky, but not impossible.
I still don't feel that you have responded to the point I made about personal freedom and the right to choose, but I am quickly getting to the point of not wanting to bother any more. It seems your aim is to continue to be right, not to communicate.
