Let's suppose only 2 pigs (m&f) left in the world. There is some bizarre situation in which you have to decide to kill those last 2 pigs in the world or just one man (among 7 000 000 000 others). If you kill pigs the whole kind is wiped off. If you kill the man 7 billion of people still left.
What do you think is more ethical? I received some strange answers from people I talked with, so I am very interested in your approaches.
