I had to say maybe Author would see this. About sins. Mc is not greedy about magic. Greed is different. Mc is prideful and mostly Lustful toward magic. His time spend on magic, gaining more power, improving what he knows. All of these action can't be corrolate with greed. Greed and Envy kinda similar in MC cituation. If he was weak at magic it could be saying that he want to own all magic items to improve himself. But he is not. He is clearly OP for people around his age. There is no reason to be a greedy.
