Hello ? Craster is rapping his daughters and sacrifying his sons ! How can anyone be a worst father ? Balon Greyjoy is nothing compared to him (plus he has affection for his daughter... I think. And even Theon, maybe).

No contest.

!!!!

And Craster and Walder Frey.

The more interesting question is who the best father would be.

I can't imagine that no one picked Walder Frey. He is a f**king jerk, but Craster also is one. Kills his own sons... Robert is just so stupid because of the Rhaegar&Lyanna - thing.

What kind of father try's to have sex with there daughters & kills there own sons? Craster is definitely the worse in my opinion, i also think Robert & Balon are pretty terrible aswell.

Craster, Walder Frey, Robert and Balon Greyjoy

What a disgusting fellow!
Robert never had a son to care about, either the were bastards or there weren't his.

He is disgusting !!!

Craster, Walder Frey and Balon Greyjoy all would be horrible fathers to have

and Balon too!

He's by far the worst father. Second I would have to put as Robert Baratheon, though, because he was cruel and neglectful, and taught his kids how to be a bad person. I blame him partially for Joffrey.

Then Stannis.
