Not very tempted, actually. In this hypothetical, since I'm not feeling empathy the murder wouldn't make me feel bad and I get money. But who says I have to decide based on how stuff makes me feel?
I might feel absolutely nothing for this stranger and still think "Having the money would be nice, but I guess that would lower net utility. I'll forego the money because utilitarianism says so." That's pretty much exactly what I think when donating to the AMF, and I don't see why a psychopath couldn't have that same thought.
I guess the question I'm getting at is, can you care about someone else and their utility function without feeling empathy for them? I think you can, and saying you can't just boils down to saying that ethics are determined by emotions.

Caring about someone else's utility function is practically the definition of empathy.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
