Tell them you don't care
From Lord Of Utterdom
"I could give a shit," you say, shrugging your shoulders. "This is no concern of mine."
The king and duke look on with disgust.
"I would rather drink and chase women then get involved with such stupidity."
The King quickly dismisses the Duke, and when he has left the room, turns and shakes a finger in your face.
"You have no respect for our history, our lineage, or your duties. I tire of your endless disregard. You were taught better than this!"
You shrug again, and the King shakes his head. "Fine. Return to your chambers and do as you like."
You do exactly that, unconcerned with the issue. You spend your time drinking, carousing, and fucking the servants, local girls, and whatever other women cross your path foolish enough to fall into your bed.
When your father dies on your 30th birthday, the crown passes into your hands. Your reputation precedes you to the throne, however, and you are assasinated the day before your coronation before you can lead the country to ruin. You are quickly forgotten by the people, and your name is barely mentioned in history, save as a sad story of the ruin of so noble a family line.
