Yup. It’s just tragic all the way around
Obviously it’s most tragic for the child who was abused in childhood, adopted by a mother who was taken in by hucksters, and then killed in this so-called medical procedure.
But it’s also tragic for the adults who were so screwed up that they thought this was helping the kid. I’m sure they will spend the rest of their lives filled with guilt, on top of the criminal sentencing, for a misguided but presumably good faith attempt to help a kid recover from a psychological condition.
