The Pentagram of Satan is the symbol that you have to worship as if it is the crucifix that you always worshipped in the past.
You don't have to ask why, it's a dogma. It gives you everything you want if you love and prey for it. It allows you to stroke your cock while watching it in its name. Be a Pentagram boy and start worshipping it now and change your life and religion forever. Welcome Satan.
