99% of these bands are just doing this to "look cool" now i will say there are REAL satanic bands that DO worship satan, however many satanists, at least today, do not truly sacrifice anything, but then again, there are three types of satanists, laveyan satanists, which dont really beleive in a literal satan, spiritual satanists which beleive in a literal satan but just scratch the surface of it, and then there are those lurking in the shadows that belong to a highly secretive organization that is probably the most real satanism there is. many of the highly secretive ones do perform real sacrifices, but none of this hits the public eye because of its secretivness. many of these type satanists arent at all public about their beleifs and you would probably never guess them. they belong to an ancient "cult" known as the brotherhood of satan that has been around since the beginning of time. they are slowly coming out of the shadows now and not all of their extensions perform these types of acts, mainly the ones deep in the "higher ups" especially the ones involved with the illuminati. no doubt they do do some strange rituals, all of them. i know a satanist who summoned a demon once and was disrespectful to it and it literally ate him. point being is no christian should be listening to this type of music, it goes against all of our core beleifs and even blasphemes our great god.
