I personally think that this is about the protagonist's confession at Alpheus' cathedral. With this, he "betrays" the Veritas-symbol on his chest, because he doesn't want to live the lie anymore.
I believe that the second stanza is from Robert's point of view, with "And tonight you die in hell" meaning that he is on his way to his brother and planning to kill Aurora.
