>>53221390And Sesshomaru's entire character is basically " I am Lord Sesshomaru and I am better than all the character because I am Lord Sesshomaru and I have the blood of two special parents. My passtime is beating up my hanicapped little brother over a sword and being attached to a little girl that I groomed as my wife"
Inuyasha was a half-demon who didn't inherit dozens of special powers like Sesshomaru and his human can't handle his full power. He also lived in hardship where he was constantly discriminated by human and Demon so his personality make sense. Even then if we compare Inuyasha and Sesshomaru action, Inuyasha often shown to more mature than Sesshomaru who is a freaking pain for majority of the time,
