Hypothetically speaking, if your death would save the life of one or more complete strangers that you know nothing about, how many people would need to be saved (if any) in order for you to give up your own life?
EDIT: Your death would be painless and instantaneous.
Or what if they are 100 people who are all lying in hospital beds with incurable illnesses that cause excruciating pain, wishing they could die, and now doomed to years more of their unbearable existence?
I would first ask them how they feel about immigration. But joking aside: In the situation itself I would probably feel different.
