Magic isn't as simple as only good people can use light magic and only bad people could use dark magic. What type of magic the user uses depends on the action and the motive. Rumple used light magic when him and Belle shared TL kiss, which means he used the most powerful light magic as the dark one. Regina used light magic after decades of using dark magic. When Emma killed cruella she used dark magic and faced the temptation of darkness in the next episode. Snow white used light and dark magic multiple times.
