Magic, normal magic. You know it and stuff, you can get away with killing in secret and stuff.
Magick, Wiccan culture Magick, or 'Witches', if you prefer. You cannot get away with it, because there is force made by the Magick itself, that if you do something wrongly, such as killing or harming someone useing Magick, the force, 'The Darkness', would do the same to you. Normal Combat-to-Combat Magick is fine, that's fairplay to the force. Cursing, or just killing the person out of your own anger, is not fairplay, and therefore the spell, thouhg going to whomever you had cast it on, would also bounce-back and you'd have it. You cannot remove it from yourself unless you have removed it from the other person.(No, the Darkness doesn't harm you for killing someone with your own hands. You have not used it, so it will not bounce the fatality to you.)
Really. I hate normal Magic, you can basically get away with stuff.
P.S. Magic to Wiccan's is Magicians, Jokes. 'Play Tricks', Basically.
