This is life:

Child "A's" daddy says he wont ever amount to shit.
The child becomes an adult, drug addict, and winds up in prison or ODs based on his fathers cruel words

Child "B" goes through the same but develops an extreme hate for his father and becomes 10x that of his father and any 10 of his ancestors.

Cream rises shit sinks.
Bad experiences make you stronger or defeat the weak.
