Um, you don't have to kill someone to remove an organ. Many people donate them voluntarily while alive. But if there's no match or no-one willing to donate, we don't extract them from, say, prisoners against their will. (Though some countries do.)

It seems like the fundamental difference in our worldviews is that you give equal significance to humans and animals, and I don't. That's why for me human organ harvesting is not the same as pig organ harvesting, and that's why experimentation on pigs is acceptable for me if it results in fewer human deaths.

Yes, that's my original point. I don't see the difference between humans and animals, especially intelligent social beings such as pigs, as so great as to justify actions which would be considered grossly immoral against a human, and I don't understand how others can.

A human and a fly? Sure, I see how one can apply vastly different moral judgements (I certainly do). A human and a pig? No, it's a matter of degrees.
