@Sylveran does this selfish actions put him or his daughter in danger? Does it go against his morals? What so bad about travelling around beating people again?
When you have this kind of power, people will want to take advantage of you, or worse manipulate you. That's the kind of employers he will get once he leave his current house.
And remember, in eastern cultures, there is an important concept: debt of gratitude. There are families that serves another family for generations, simply out of this debt. Unless there is a very good reason, leaving make him an immoral, ingratitude person.
@womangadex he's clearly modeled after people of the Middle East.
