When it comes to the Devil, I love focusing on the version of the story where he is simply punished and banished because of wanting Freedom, his rage, his indignation and his irreverence.
Western stories need better plots about the Devil, the manga/anime Black Butler, comedy aside, did a terrific job, not a simple beast, but a powerful, sentient pre-human, or as the series 'Penny Dreadful' put it on a dialogue that made my heart melt: "... If you have been touched by the demon, it's like being touched by the back hand of God. Makes you sacred in a way, doesn't it? Makes you unique, with a kind of glory. ...". Aye!
The Devil prints can be found here, and a new, better version is due soon.
