You wake up trapped in a room with 2 buttons. The first has your name written on it and the second has a number X (edit: X>0). There are instructions on the wall that say that pressing the first button will cause your death and pressing the second button will cause the deaths of X people in the world. You cannot escape the room until you press one of the buttons. How large must X be before you press the button with your name on it?
For the sake of argument:
1. X people are randomly chosen from the entire world. A farmer in India has as much chance as being selected as your best friend or child. You have no way of knowing who will be selected until after you've made your decision.
2. You are guaranteed to not be selected as part of X
3. No one will ever know that you were forced to make this choice
4. EDIT - Death is instant and painless for whomever you choose
Bonus round:
How does X change if the entire world knows what choice you made?
EDIT2:
For myself, I'd probably have to get to close to 1 million before I sacrificed myself.
If everyone knew what I did, I'd probably settle for around 10,000.
