Thanks。。。here...

So why did Adam Lanza kill 20 innocent children and any adult who got in his way? Sandy Hook’s Elementary School children had what Adam Lanza didn’t have. Sandy Hook’s Elementary School children had two parents, they had teachers that cared (unlike Adam’s high school experience), they had each other, they had laughter, they had hope, they had love, and they didn’t have pain. All enough reason for Adam Lanza to kill them. If he couldn’t have what they had, they had to be destroyed. One of the most lethal tunnel visions anyone can have.
