True demons have hollow souls, they do not know love, they cannot cry, they only know pain, fear, and worst of all hatred. Sebastian never felt that, When he see's his father as a dusty corpse he starts weeping "I WAS FRIGHTENED! How can God love someone like me, the contract, the plauge, EVERYTHING! I USED PEOPLE! I WAS SCARED OF HUMANS!" then he hears his father's voice "hahahaha...is that what this fuss is all about? You think God hates you because of some petty contract? Or what someone made you do? How can he hate you if you are able to cry? Didn't know know a true demon is unable to cry?" the idea came from Hellsing when Anderson dies "True demons soul's are hollow, they know nothing but hatred, pain, suffering, and fear. You and others like you are renegades, your soul is full, you never wanted to consume an innocent soul, didn't you spit them out after the plague? Then didn't you run away? You defied the devil, you weep, you laugh, you smile, you care, you feel. God cares about whats in the hearts of humans, angels, renegade demons, all of us, so smile, smile like how your mother used to. what are you and Ciel going to do?"
Sebastian wiped his tears and smiled
"Probably set some new goals, dreams, continue our lives...see you and mother at the pearly gates one day...father dearest."
Then as the body breaks away "I can hear her, your mother, and Vincent....all of them wait for me...remember to forgive those who trust pass against us...amen..."
Sebastian holds his mother's rosary "...Amen..."
then the church bells ring and a crow follows a dove indicating the redeemed one-sebastian's father-is in heaven with his mother. Count raum consume Vincent and The Redeemed one's souls Sebastian set them free and stopped the mass possessions in new york city sebastian himself was at peace
