More like McVeigh than we know?

Sadly, an unstable home life seems to lead these madmen to blow their everyday grievances out of proportion.

The estranged father of the anti-immigrant extremist arrested for the mass killing in Norway said in an interview published Monday that he was shocked and despondent over the news and that his son “should have taken his own life, too.”

Mr. Breivik’s father, Jens David Breivik, is a retired career diplomat who divorced the suspect’s mother more than 30 years ago.

So the boy was two when, perhaps, his traditional world was shattered. And perhaps because he couldn't cope in life, he found a way to blame others, the newcomers, the government that permitted them in.

Sounds like McVeigh to me. Grievances against the world that no one could quell.

McVeigh, a militia movement sympathizer, sought revenge against the federal government for its handling of the Waco Siege, which had ended in the deaths of 76 people exactly two years earlier.

McVeigh was born in Lockport, New York, the only son and the second of three children of William and Mildred "Mickey" McVeigh. His parents divorced when he was 10 years old and he was raised by his father in Pendleton, New York.

McVeigh claimed to have been a target of bullying at school and that he took refuge in a fantasy world where he imagined retaliating against those bullies. At the end of his life he would state his belief that the United States government is the ultimate bully. Most who knew McVeigh remember him as being withdrawn, with a few describing him as an outgoing and playful child who withdrew as an adolescent. McVeigh is said to have had one girlfriend during his childhood, later stating to journalists he did not know how to impress girls. According to his authorized biography, "his only sustaining relief from his unsatisfied sex drive was his even stronger desire to die."

While in high school, McVeigh became interested in computers and hacked into government computer systems on his Commodore 64, under a handle – "The Wanderer" – borrowed from the song by Dion DiMucci. In his senior year, McVeigh was named Starpoint Central High School's "most promising computer programmer," but maintained relatively poor grades up until his 1986 graduation.
