Calus is a horrible father and Clovis is somehow worse in every way. Crow isn't even a dad. Uldren unintentionally wished for Riven to raise Fikrul from the dead. Riven would be more a parent to Fikrul than Uldren, and I wouldn't say Riven is a parent in that way. So Rasputin would be the only parent left. Rasputin's son was killed in The Collapse. Rasputin killed Felwinter, who Rasputin saw as using his son's corpse. I'd be pretty pissed if anyone wore the corpse of anyone in my family. And if I was a Warmind that has had virtually no socialization, I would be violently irrational too. From what I know, Rasputin was a fine father that wanted their son to experience humanity for the both of them. He then went on to kill someone who was using his son's body alongside nearly all of his friends. That's the bad part, but it was a very long time after his son died.

Unironically Crow. Calus might love Caital, but he’s also a Narcissist who abused her. Clovis is Clovis. Rasputin got so angry that Felwinter became his own being that he enticed the Iron Lords into the Plaguelands before slaughtering them all just to put Felwinter down. Crow might’ve killed Scorn, but the scorn can come back (with Fikrul) and he tried his damndest to make peace with Fikrul. Him dying then coming back as Crow wasn’t a fault of his own.
