"new world gone slay the Devil"
might mean since religion is becoming less serious & people are caring less & less, the devils importance has been reduced to a Halloween costume
the ol' fire & brim stone shpeel isn't scaring people into submission much anymore
"new lovers bang the corpses"
sounds like not being able to let go of the old life,
like they didn't love life until it was gone,
so it's not the lover that's new just the love that made it it
