Wicca
The main Wiccan moral teaching is called the Wiccan Rede. The word rede means "advice" or "council" in Old German. "An ye harm  none, do what ye will" is the very basic Wiccan Rede, which means, "Do what you want to do, but do not harm anything in the process." This is most likely based from Crowley's "Do what though wilt, shall be the whole of the law".This means that you must think about how your actions will affect other beings and yourself.
