He stabbed someone dude. This isn’t a “maybe I should scold him” situation. He was also regarded as the hero, and has fucked up multiple times since Ruck left his party. It’s not getting “mad along with him,” it’s he needs to be put in jail NOW.
which is why the father bailing him out of jail is debatable. Family is expected to be more lenient with crimes but, yeah, he stabbed someone so you could argue that, rather than cutting him off, his dad should have just left him in prison. Families typically don't work like that when you do stuff like this though.
However, everyone else isn't supposed to be dealing with that. The guild leader is just a guild leader, the store owner is just a store owner, kicking him out or demoting him is what they CAN do, THEY can't rearrest him. Though as we are about to see, they can beat his ass and send him back to jail after if he gets violent.
Further, you're normally supposed to have recognized what your crime is and shown better behavior before you're let back out early. Basically, they're drilling into him the understanding that he was supposed to get before he was out and about, telling him how shitty a person he's been. Honestly, if the GM tossed a violent guy like him out on the street without even pointing out his behavior it would be gross negligence but he's already been released by his daddy so he can't be detained.
