Why did Merlin ask Uther Pendragon for his son as payment for letting him sleep with Igraine? The entire kingdom wouldn't have been swept into turmoil had Arthur stayed with Uther at the time of his death, and no one would've challenged Arther's ascension to the throne since they knew it would be Uther's son. Merlin threw the whole country into turmoil for Shit All reasons and gave nothing to show for it. Why the Hell would Merlin do this?
