I don't really dive into Eddie's childhood, but suffice it to say I believe the experiences a child goes through are absolutely fundamental to their development, their psyche, their understanding of the world and socially acceptable practices. A parent's interaction with their child and how they treat them are critical to growing an adult who is able to balance the challenges of the world mentally. It's not just Nature vs Nurture. They are both a huge factor, and I would argue Nurture may be the larger component.
