In regards to the shooting being evil.. it was mostly the result of complete negligence. If his mother knew he was on the Autism spectrum then she shouldn't have introduced him to guns in the first place.
That is a flawed if/then argument. Experts say Autism and Asperger’s are not linked to violence:
Aggression in people with Asperger’s and autism tends to be more reactive, such as “impulsive outbursts, being quick to anger, shoving or pushing, shouting in anger, and being slow to cool off when angry,” said Butter, who is also associate director of the Child Development Center at Nationwide Children’s Hospital in Westerville, Ohio.
The types of violence seen in Connecticut and elsewhere “have occurred at the hands of individuals with a range of psychological profiles, and the underlying and connected theme is that we have not done enough in our schools and mental health services systems to identify, assist, and de-stigmatize those people suffering from the illnesses of the brain,” Butter said.
Added Dawson: “Whenever there is a horrible tragedy like this one, people want to make sense out of it and they’re trying to look for answers. I think it’s important that we be very clear that if this individual did have Asperger’s or autism, which we don’t know [for sure] that he did, this is not going to help us understand what happened. Because there really is no link between the two.”
What happened at Sandy Hook was evil. Pure, disgusting, unthinkable evil.
