Good work ;) But I think it's impossible to have an archbishop of Envy, while Satella is alive.

In my opinion, the power of Envy is about love. More you love someone, more you become obsessive to take back something precious to that person.

Maybe Satella becomes insane after taking the Witch's genes, because she loves Flugel / Subaru. That's why her own ability affects her, so the Witch of Envy / her alter ego is created.

The Witch of Envy had killed other six witches and destroyed the world, like anyone else who know success (about achievements) and happiness (about life goals) must learn fear to lose something precious to them and experience death.
