&#62;Why not? It might make you worth a little more as a human being, all other things kept equ<p>No, it wouldn't make you worth any more. To make this more concrete, are you seriously suggesting that given the choice between saving the life of someone with bad skin and saving the life of an otherwise identical person with good skin, you could cite skin quality as your justification for choosing to save the one over the other? Clearly, the dilemma in this case would be just as acute as in a case where you had a choice between saving one or other of two precisely equal people -- it would be grotesque to suggest that skin quality could act as a tie-breaker in such cases.<p>I suppose it might look from your perspective as if there is some kind of weird "taboo" on judging people, but really it's just that you're doing it wrong. People aren't valued according to a weighted sum of their qualities and virtues. (Of course, you can weight their qualities if you like, and you can sum the results if you want to, but the result will serve only as a measure of your callousness.)
