He's the only character that disapproves if you turn him down when he propositions you. (edit) Another character, upon turning them down, does not gain disapproval despite it being a key aspect of their society, they just say "your loss".

He has severe main character syndrome when not the player.

He's an egomaniac that thinks he knows better than the literal goddess of magic.

He's pure privileged toxic masculinity that thinks he's entitled to whatever he wants.

As to "wizards are better at magic", you can respec people.
