Christians: I'm still looking for a biblical reference to Satan doing something evil, has anyone found one?

Sympathy for the Devil. Mick was right. Bad rap, bad P.R., heavenly spin-doctors painting testimonial pictures of a soul whose intentions are good, but oh Lord, intentionally misunderstood, erstwhile angel of light. But then, I've always considered the source and I don't truck with any monster that will drown every living thing on earth and then go "oops, here's a rainbow."
