I agree. Yes he is charming and sometimes cut but totaly crazy. On description up to now his parents are normal and kind so no excuse there for his crazy behavior and abusiveness of his brother.
The only reason i can come up with for his crazy is maybe multiple kidnapings...? And i really hope the excuse is not only that he is and alpha.
I really can't see anything helping his case, what about you all?

Why are everyone saying poor guy like this guy didn’t trick his brother to think he fucked a dog during his rut and has been abusive to him . Idc if his mind doesn’t work properly its not like he has any functional illness you guys are so forgiving
