In fairness, mostly he does that to landowners who oppose him, which is a worthwhile distinction...but everyone's taxes definitely go up at the very least, and he's definitely not super friendly. We'll have to see what the guy himself is like on the Vestfold trip. Influencing him for the better seems potentially possible, depending on what stage of his life he's in at this point.
The big wrench in the plans is whether he's a Steelfather yet, because he probably is by the time he's king, and if he's one already, well, we both won't like him, and won't have a good way to kill him. We'll have to see.
