Review Detail of Levianeus in The Seraphim is Among You (Hiatus life is calling)

Making your mc have a ' benevolent and righteous' character is quite boring. It would be more interesting if the mc was cunning and ruthless and had to fight his better nature to attain his goals. If not remember that angels are on the +500 morality scale so please add some of his internal struggles just like Ainz has with his immorality.
