Many agreed, but the light side tried to argue that the class was not necessary and was dark, because they would learn the true meaning about having a light, a grey and dark core, but no one was able to provide any good reason since many debunked the theory about that anyone with a dark core was evil, whereas someone with a light core was good. It was proved with actions of James and Lily, which was another sore point to the light side. The class was put to a vote and it passed. The class would be taught from first to seventh year.
