Is anyone familiar with the song, "Angel of Darkness" by Alex C.? If so, what is it theme or meaning exactly? What is the story behind the song?

To me it’s about someone whose been deeply betrayed in their relationship. They feel their whole world has been shattered and the light of that love has gone out. But they won’t allow it to over come them, they are determined to get past it and find that light again.

Maybe the dark angels have been banished by heaven and they were so angry that they won’t let the light to come to their teritory. They were sometimes the guardians of the night and also guide the poor children who were orphaned, sick, or abandoned. They were not devils, they are the most kindest angels of the darkness. They tell the people to never give up to fight until the end and set the freedom. But sometimes the dark angels supposed to be evil and kill people, that’s the true angel of darkness, mysterious, evil, but kind and warm-hearted :)
