I don't think the writers ever though Blue was evil, however Keegan confirmed at a convention that she originally played the character as morally ambiguous, because she wasn't sure, which is probably why people think she is shady and possibly evil (well that, and the fact that the writers gave her some questionable lines and actions in certain episodes).
