Satanism is worship of satan. Satan is the devil. Put two and two togetherNo and "Satanism" isn't "Devil Worship"
There are different types like for instance Non-theistic Satanists don't worship the christian devil they are more humanistic.Satanism is worship of satan. Satan is the devil. Put two and two together
Now as for slayers and disturbed, I love that kind of music, such lyrics, much wow. Dem dark lyrics.this is an decade long argument,lets just say music is an expression of yourself. as general this is true, but how we interpret the songs are due to individualism, if someone say's hillsong is illuminati would you believe it also? metallica and other rock bands only wants to express how they interpret their environment and their interpretation of what they feel.
None of their lyrics are satanic.They can be considered Satanic depending on interpretation of their lyrics.
