"This sentence reflects an unthinkable betrayal by parents who are meant to protect their children from harm. Pearlene was denied the chance to grow up and become who she was meant to be. There is no punishment that can restore the loss of life."
It's been a theme in letters I've seen this year-adults complaining that children aren't processing the difficult things they go through in the way the adults want them to. 15 is a really hard age for a lot of kids, let alone for those who've seen two fathers exit their lives (to varying degrees). He's processing a ton of changes in his own life, possibly entering high school, and he shouldn't feel responsible for the feelings of his ex-step-grandparents.
