He's just doing what his own father did, so you can't exactly blame him. He went through the same thing- He had to kill all his own siblings to get to the throne-
He wasn't supposed to be a good father to begin with. Since, the tradition is to let them kill each other. Imagine if he gets attached to all of them and watches all the children he loves dies one by one.
I know but i still dont like him. I feel unfair and sad to the children's who are dying everyday but he never really care about that. Whatever excuse reason that makes him force him to be like this it doesn't change that he is still a terrible father.
I still dont like him..his a terrible father ╮(￣▽￣)╭
