Had mine for a few days, didn't think to post it.
Mine is a bit deep... As many of you don't know, I'm a aspireing writer. "Cyanite" is a character of my creation. She's basically a witch who plays god (a least in one of my stories). She's consitered to be a God of Mischief; Helping or hindering those she meets on a whim, purely for her own entertainment. Because of this, she is both prased and feared.

This saying essentially means that "A bad person can also do good, while still being bad." (Rather; you can't judge a person, and people are unprediactable.)
