Magic itself is neither negative nor positive; it is simply energy. People often refer to negative or positive magic, but what they actually mean is that the intention of the person doing the magic is negative or positive— the terms positive and negative magic are a shorthand way of speaking. Black magic is another term for magic performed with a negative intent, and white magic is often used to describe magic performed with a beneficial intent. Both forms of magic have ethical considerations that can shift a seemingly positive spell into the realm of negative magic. Manipulation, permission, and personal benefit are all elements of magical ethics.
