Honestly the edgyness/coolness factor would just increase if he was a badass evil ninja mastermind instead but I would definitely want to self insert myself less because it's lamer than having magic powers. I'm still a sucker for self made powerful main characters even if the methods are dubious. I like to root for hard working characters even if they're evil, while I get annoyed at a lot of good characters that are lazy. This MC broke through thousands of years of genocidical survival trauma to unlock magic, it will never not be cool to me
