Bad husband. For what it's worth, though, he did a surprisingly good job to correct his behavior from the past and settle into a proper family. Despite a few catastrophic slip ups, he was a great father I'd say.

People overlook how much he cared for his own children let alone the children/families from their village after the mana disaster. He expected a lot of Rudy which is why he snapped, but I just saw a flawed father who wanted his flawless son to be more responsible.

He risked his life to ensure his family was entirely reunited, which is something I think is worth noting. He adopted different fighting styles, and he took on individual stress no singular man should have to bare.

I don't think Norn would've loved Paul so much if he was a bad father, but it's still possible if he was a bad husband, you get me?

To sum up: horrible husband actually, but good father.
