(view spoiler)[Who did the raven kill to make him a murderer, as predicted by the prophesy? Did I miss something during the final fight scene (Cath killed the Jabberwock, and I don't think anyone besides Jest died in that scene)? Or was it his execution of Peter at the end (which may or may not be murder, depending on how you look at it)? (hide spoiler)]
Lucia Yes, Raven acts as executioner, but the King's court has already declared Peter "not guilty." Cath revolts against the verdict and orders Raven to execute Peter. It's murder because Cath is not delivering justice, she's just getting revenge, and Raven decides that he'd rather have revenge as well, so he goes along with her.
