I'm not sure if it's actually true that he said that about Adam. There's no footage of his father, Peter Lanza, ever saying this, it's only supposedly from a "new interview" they had with him back in 2014:

Adam Lanza is one of the most fascinating people I've read about. Dude's whole life is mysterious...we don't know a whole lot about him and not even that many pictures of him exist. I've felt really sorry for him since the day he made his mark on this world. Just reading about his life, and how much he "didn't fit in with the others"... this world is so cruel to people sometimes. Look at what society did to him...
I wouldn't say he's the ugliest person I've ever seen though. Maybe one of the skinniest men I've ever known? His body dimensions...scare me. 6ft tall and weighing 112lbs at the time of his death. How the fuck did he manage that?
