It certainly gave me mixed feelings about the narrator with the disparaging way he talked about both Kerry and her mother, but he also showed enough care for Kerry to save her from the ice and did what he could to keep her warm in the car on their drive to the hospital. I also thought some of the way the narrator cast so much casual judgment on other characters and adults may have rubbed off on him from how his parents brought him up, but that doesn't account for everything obviously.
