I get Kane is a good man, but they are in a world with magic and monsters in a medieval setting, there's no way people acted like that in those days, much more when there are practically transcedents/demigods, even gods, walking on earth left and right.
Those type of values where reached only now when there's plenty of resources and technology to provide to every person, back then? Not so much, especially for people with criminal record. I'm not saying people should not be forgiven and give a chance to start over, but things just didn't work like that in the past.
