I think we'd refer to ourselves more in the Nietzschean understanding of beyond good and evil, as opposed to being the wilfully destructive element you appear to be advocating.
We don't strive to be "evil" people and have no drive for "creative destruction" and we don't believe Satan to be a "real entity"
It can be said that Satan is the life-force, or the libido though. So maybe it's a matter of semantics in your description.
Human beings are as significant as a cigarette burn in the sun.
