Agreed. It would've been better not to have included terms such as "light" or "dark" magic in the show at all. Light magic is simply harnessing the magic of true love, as we've seen Regina do against Zelena. Hypothetically speaking, anyone that has a true love and can use magic should be able to wield light magic, regardless if they're evil or not.
