I always just didn’t really like him and a lot of people don’t really like him either but a few of the reasons are he did a lot of bad things I’m the manga and he really hurt Emma and I think he drank mujikas blood. There are plenty more but yeah
I don't think Norman drank Mujika's blood because when demons degenerate they drink Mujika's blood and Norman ain't a demon but he learned his lesson because of Emma
