The wiccan rede states that any harm done to anybody else means that it comes back to you three fold, this is one of the most important laws of the wiccan rede, because it not only states what you can and can't do, it puts you in your place. It also shows that wiccan is not an evil religion and defies alot of respect into it.

HARMFUL SPELLS THERE IS NO SUCH THING anyone who performs evil magick is not a REAL WITCH.
