Was he a good dad? Nope but was he really all that terrible especially by one piece standards
What he did is like the equivalent of irl parents giving their children a whooping and grounding them
I don't think you got Kaido's whole character very well tbh.
If you want to make irl comparisons, Kaido is a barbarian general who enslaves countries, on top of that he's a poor father that drinks his sorrows & tears because of his past (Oden) and beats/locks up without food his daughter for trying to impersonate that very past that troubles him.
He wasn't just not a good dad, he was a straight up bad dad.
Not the most evil character in OP tho, I'll give you that.
