If he protects people like this, then people will serve him for that protection rather than love for him.
However I learned a great lesson when watching Game of Thrones Battle of the Bastards.
When Ramsey was captured, Sansa said she will feed him to his dogs.
Ramsey said his dogs are loyal to him and wouldn't hurt him.
Sansa replied 'You haven't fed them in 7 days'.
No matter how loyal one is, they think of their own survival. If he didn't feed his dogs in a week, they will feed on him. Why would someone be loyal to someone who does not take care of him?
Loyalty is two way street.
