Do some people “deserve” an organ more than others?
“Do some people “deserve” an organ more than others? How about someone who has already received one organ? How about a mother with young children vs. someone who doesn’t have children? How about a suicidal patient who has organ failure b/c they tried to kill themselves? What about someone who is a life-long smoker and heavy drinker? Please include discussion on what you view as appropriate methods/criteria for determining who receives an organ”
