These types of questions are stupid because they're asymmetrical and unlikely to exist. Its a lose-lose no matter what.
Jai, you think all life is equal? That's something interesting. :D
Here a questions on a decision that have happened countless of times:
What would you do from your current perspective if you were part of a small tribe living in an arctic environment living from vegetarian fish?
A. Live on and kill countless innocent vegetarian fish.
B. Starve to death.
C. Kill your small tribe(including yourself) at night to save even 100x more countless innocent vegetarian fish.
A. The decision most people would choose, but when truly seeing the life of a fish equal to the life of a human, than this is the most unlike decision.
B. The decision where you do not kill any life directly, except your own.
C. The decision where you save most lives(really a lot), but also have to take a few lives.
