None of us are perfect. We find things that make us sad, feel hurt or have some physical pain. We can all find a reason that something about life isn't just right and some people want to murder themselves because of this. How much pain is enough? Who decides? Can a person say a little mental pain? What about depression? What about physical pain? How about a hangnail?
There is a difference between life support. (shelter,food, air and water) and the machines that filter, pump blood etc..
To take a person off of shelter, food, air and water when they or someone else can help keep them alive would be wrong for the responsible person in any stage of life. To stop using machines that replace body parts or functions of the body when a person is in pain is different.
To remove the basics of life deliberatly would be neglect or murder but to force a person to stay alive as a cyborg in pain would be wicked.
Focusing on money would be selfish.
