Right, we have to draw a distinction here. I'm talking about how we define what's more ethical. That doesn't mean you're going to live up to that perfect ethical standard. You can say, in general, people's lives are equally valuable, and that knowing nothing about the two groups, you'd prefer two people died instead of three. Of course, in reality, we're not perfectly ethical, so we're always going to be choosing the set of three if we're in it. That doesn't change our definition, though.

So if this "ethics" thing dosen't describe our preference properly... uh, what's it for then?
