Betrayal in Metal

Betrayal in metal would be a very extended topic. I like this idea because after going through my playlists on music sites, most of my music is metal. Metal also has a lot of meaning to it. One main topic that metal focuses on is betrayal which is why I feel this would be an understandable theme-genre for me. I already know many songs that may have betrayal in some of my metal music, so this should be a very possible theme-genre.
