My own opinion is that NG is not a candidate for rehabilitation.
I think he needs help; but only behind bars --- and should stay there for the rest of his life.
Sounds harsh, but it doesn't get much worse than this.
Nehemiah must have played with those younger kids. and did normal stuff like eat breakfast cereal together in the mornings, etc.
And then go murder them ?
This horror reminds me of the killings in Sugarland, TX. Bart Whitaker or something ?
A little different in that Bart was older ; but still he planned the murder of his entire family. The dad survived.
A little off-topic but wanted to add.... I didn't date at 12 yrs. old , wear makeup, or high heels, either --- too busy being a tomboy and just enjoying life ! ( plus my parents wouldn't have allowed it

)
Anyone who thinks this teen should get out at 21 yrs.-- or even later in his 30's -- is welcome (imo) to have NG live with them !!!!
That might make anyone pushing for leniency , to change their mind.
