Jake hated his father for the person he was, but he never hated him for the unreasonable hatred that he felt for him. He was the man who caused the death of his beloved wife… While Jake never had the chance to see how his mother looked and his father always his the photographs of her, he still felt to this day some blame for that incident.
In his place, he believed that he would try to be better, but for a man to keep moving his wife for many years even after her death to the point that he never got into any relationship after, he could understand how much his father loved his mother. That was his sole redeeming trait.
In the end, Jake didn't want to believe it, but even before the memories of his birth, he found new ones. At first, he only saw darkness, like it was the time between the two lives that he had supposed to leave… memories of the void that Myrna mentioned.
