The appeal to goodness is that it attempts to absolve our baser tendencies.

A related perspective is our anthropomorphization of animals with that same goodness. Bambi is a great example. In that, the animals were all utopic, but the humans were pure evil. Notwithstanding that, to the Owl, his Squirrel and Chipmunk's friends were actually food. I use that example because we did it all the time with animals, and we turn and do it to ourselves, too. It's the language of 'could,' 'should,' and 'ought.' But that language, ignoring the proclivities, actually makes the evil manifest.
