Maybe in the short time before he killed him himself he truely regretted how horrible he treated his cousin. Considering by the time he recaptured him, all he wanted was for him to stay by his side even if he didn’t love him. So maybe the spirts and gods took pity and also gave him Karma. They’re blood brothers, they’ll always be close, but he can never love him.
Why did the asshole King have to be reincarnated too? If it's true that you are reincarnated based on how you lived your life then he should have been reborn as a deformed worm crawling on the bottom of the deepest ocean floor, forever trying to escape the crazy fish that live down there.
