If I were to decide that what was beneficial to the human species was to eliminate all non-beneficial members of society (i.e. mentally and physically ill, old, and homeless people among others) and go around murdering them all, how would you be able to tell me I was wrong? Because you felt empathy for those people? What if I said that I overcame my empathy to aid the human species, because those people only held others back and I was doing others a favour by ridding them of useless people. What would you say to that?

If you decided that ^ you'd have a lack of empathy/humanity.
