His relationship with his other son seems relatively unknown, but from what is shown in the Five Nights at Freddy's 4 minigames, he is uncaring and neglectful towards him, letting him get bullied by his older brother at home and at work.

This is likely to hide his true intentions and evil mindset, while showing that he is a manipulator and seemingly theatrical, being able to easily put on a character to fool people. The fact that he created the Funtime Animatronics, which are very advanced and technological, shows that he has a genius level intellect, a talent for robotics, and is very proud of his creations. He is also fascinated by how they have changed after the events of Sister Location.
