I believe that "perfection" is a loaded concept, because it can be made to imply exclusion: "never broken" is a very different proposition from "finally fixed," and fairly useless in this context. I'd be satisfied with "better." I don't believe I've ever met an evil person, in real life or on this show.
I think the people that love us are only capable of shining what was already there, but you can trust the people that hurt us to burn off the crap, if we let it. And I believe that our world, and ourselves, only get larger when we burn off what doesn't work. And someday it'll hold us all.
