The father of Sandy Hook Elementary School shooter Adam Lanza said his son's actions couldn't "get any more evil" and that he wishes his son had never been born.
Peter Lanza told the New Yorker magazine that he believes his son, who shot and killed 20 first-graders, six educators and his mother in December 2012, would have killed him too if he had the chance.
But he said he doesn't think what happened in Newtown, Conn., could have been predicted; Peter and Nancy Lanza both believed their son was non-violent before the shooting.

Speaking out for the first time since he released a statement in the immediate aftermath of the shooting, Peter Lanza said he thinks constantly about what he could have done differently, while also wishing he had pushed harder to see his son; the two had not spent time together for two years before the massacre.
"Any variation on what I did and how my relationship was had to be good, because no outcome could be worse," he told the New Yorker during one of his six separate interviews with reporter Andrew Solomon.

“You can’t get any more evil. How much do I beat up on myself about the fact that he’s my son? A lot,” he said.
Peter Lanza said he isn't interested in mourning the little boy he knew long ago.
"You can’t mourn for the little boy he once was. You can’t fool yourself," Peter Lanza said of his son.
The father added that he wished his son had never been born and that it was impossible to remember him as anything other than what he became, according to the New Yorker.
Peter Lanza said he believes Adam might have been schizophrenic and is willing to provide his son's medical records to the state commission looking into the case in order to shed further light on his mental state before the massacre.
