Nephilim: Angels and Demons

Jonathan Christopher Morgenstern.

He was an experiment. A shadowhunter with bloods of both Angel and Demon. A weapon of his father's and a monster to his mother. He grew up with only his father for his mother left him. He was raised cruelly and was trained in secret and in seclusion from other shadowhunters. He was shown no mercy or affection by his own father. The blood in his veins made him different from any other shadowhunters. He was the best of the best if he weren't in hiding. Due to the demon blood coursing in his veins, he became a cold, heartless, and bloodthirsty psychopath. However he can somehow show certain affection for his father, he was who Jonathan ever had in his life, or is he?
