How is Ranon bad?I don't get it.
He loves his wife, He does not want  anyone or anything to hurt her..(even his own kids} 
The third child is destined to kill the mother, Aina.
So naturally he plans to off the child
But apparently he is the bad guy for wanting to protect his wife, at all costs.....from fate.
HOW is he the Bad guy?!!
