The meaning that I feel the lyrics are trying to convey is that it's ok to be depressed, it's ok to kill, maim and slaughter, because your ok and I'm ok. I'm glad the rev is dead, one less devil worshiper on this earth, if he thought he was depressed in this life, I'd like to ask him if he has any regrets now that he's burining in hell along with the many people him and his band of demons have deceieved.
