If it were Tamlin he would come in and freak and stop the fight saying Feyre was to weak to fight then the thing Feyre is fighting would say " Really, cause we've been fighting for ten minutes and I'd say she's winning "
So the night court is sadistic yet Tamlin is the one who has a set of illyrian wings in his bedroom. But excuse me the night court is sadistic! No the night court is sadistic. but not the court of dreamers.
Feyre is brownish blonde, but she is a blonde. A tool is not a villain, and as far as I have seen, Tamlin has never been painted as a villain. He is the most hated character, but that does not make him a villain.
