OK, so, force is moral if the suffering inflicted is outweighed by the suffering prevented?
Does that sound acceptable?
It's difficult to know how much "suffering prevented is", especially if it lies in the future, so it's a bit problematic.
But yes.
A lot of people are dying because there isn't enough organ donors. By killing you and distributing your organs, we could
save a lot of lives. The math is pretty simple in this case. Would you support this idea? Or are you an exemption to
your own rules?
I give you that you have created an example that's difficult to answer, but
a) there are ways to solve this problem without killing someone (thus creating less suffering)
b) organ donations are very risky and it's far from safe you've rescued the other one
c) choosing the one "who should die" would be a hell of a task and I cant see anyone having the "expertise" to decide
Let's rephrase a scenario that's more sure, it's also a well-known one:
A plane with 100 people on board is hijacked by a terrorist, no way for the passengers to do something about it.
It's heading directly to a big nuclear plant or sky scraper, when it does there will be 1 million victims.
You have the option to shoot the plane or not to.
I would agree on shooting the plane, even when I'm on the plane (at least if I manage not to panic).
(I know a lot of people are gonna disagree with me on this one)
