Your character is basically alright as well. But I have to ask why does he get the benefits of being considered a rightful ruler by his NP of he stole it instead of being given it rightfully?

Not so much stole as conquered and took as spoils of war, but the two things aren't really connected. He's the rightful king of England, and the stone offers its benefits to any rightful king, even if they aren't its proper owner. After all, it went from Ireland to Scotland to England just fine.
