Okay this part I find really dumb because all of this would have the authorities involved.
I can buy that a grade-schooler may be let off for murder by the time they're in high school given crimes of passion, psychological treatment, and complexities in the law, which is why its rare for them to be tried as adults as complex moral reasoning hasn't set in. HOWEVER, the fact no one has contacted the police, informed them to what's going on, AND THAT THE MC HASN'T WARNED THEM OR TOLD THEM WHAT HE FEARS COULD BE HAPPENING, ESPECIALLY WHEN HE GOT A CALL INDICATES HE'S FUCKEN DUMB.
