For an author, the nice characters aren't much fun. What you want are the screwed up characters. You know, the characters that are constantly wondering if what they are doing is the right thing, characters that are not only screwed up but are self-tapping screws. They're doing it for themselves.
Terry PratchettThe stories never said why she was wicked. It was enough to be an old woman, enough to be all alone, enough to look strange because you have no teeth. It was enough to be called a witch. If it came to that, the book never gave you the evidence of anything. It talked about "a handsome prince"... was he really, or was it just because he was a prince that people called handsome? As for "a girl who was as beautiful as the day was long"... well, which day? In midwinter it hardly ever got light! The stories don't want you to think, they just wanted you to believe what you were told.
Terry PratchettThey know that people need witches; they need the unofficial people who understand the difference between right and wrong, and when right is wrong and when wrong is right. The world needs the people who work around the edges. They need the people who can deal with the little bumps and inconveniences. And little problems. After all, we are almost all human. Almost all of the time.
