Gluttony
If I get out of his with a working windpipe and vocal chords, I'll educate you myself, Brother. I'm not the one sent to Hell the most for nothing.
Pride made Lucifer fall, Envy for that of God's love that would never be his, Greed for such thoughts and power to behold if all was his, Lust for the pleasures that powers would bring him, Gluttony to make it all not enough, and Wrath for those that dare to object him and to bring terror to his reign.
Brother, you feel this connection, because we influence him so. There is no limits for those that are supposed to be mere concepts.
