Well I know exactly what you are saying I think.
I believe there is a state beyond good and evil, but the good is the only way to reach it. When good is second nature or even your primary nature, then you are there. As you said, these people create morality.
The problem with the dichotomy of good and evil, is that the "good" people are often capable of much greater harm in the world, because they have a feeling of superiority, and self-righteousness. There then arrises the mentality that the ends justify the means. Whereas one who is truly beyond good and evil, is simply saturated with good to such a degree that they no longer despise evil, but treat it with the necessary compassion and wisdom. I think in the west, we need a shift from the dichotomy of good and evil to one of ignorance vs self-awareness.
It really is the same thing, but without all the "right/wrong" stuff.
People only do evil because they do not understand the consequences, not because they are "bad people"
It does seem that the autistic spectrum generates a lot of natural-born philosophers, and deep thinkers in general, but we still have our share of human frailty.
You should check out Dostoevsky's "Crime and Punishment" it is mainly a response to Nietzsche's ideas about good and evil and the "superman". A classic and excellent novel that I could hardly put down.
