I suspect there is a possibility Juri was intended to marry him, but she was too independent to be told who to marry. I definitely don't think he was always like that, I think he got bitter over time, up until the time he stole their child, he had a good relationship with Juri and Haruka, that's ~3000 years of good relationships then. So he can't have acted out too much before then...
