Good Darkness

The exact opposite of Evil Light; those who fight for and/or use the light aren't the only ones who are good. Sometimes, a hero can tap into the so-called "evil element" and use it in many ways to save the day, such as casting shadows, using Reaper powers, ect.

Like Evil Light, Good Darkness can come in many forms, such as people gifted with dark power that are actually regular people, or people cloaked in darkness who help others.
