You completely missed the point.That is really nothing but a hint that can mean a number of things, from the father being ,reincarnated/time traveler/esper of some short/etc to just a paranoid man who had a bad dream.
Also it's quite silly from a narrative perspective to have anyone estrange and ostracize the one person who can do something that can potentially destroy you.
I've seen a ton of other such narratives where someone is trying to avoid a known future where it ends bad for them.
If it's a stranger they just try to avoid it. If it's unavoidable then try to befriend, cajole, enamor etc said person.
But never such a thing as isolating that person and giving it the cold shoulder. And that's because such a move is making it all but certain that it will have no qualms to bring you down, if for no other reason than just out of spite for isolating it whilst giving its sibling everything.
It's not about his daughter "potentially destroying him", it's the opposite. He doesn't care that she might hate or destroy him, he cares that she doesn't become a victim herself.
