I think McVeigh was one of those people who are looking for validation.  Because he was a little strange, a little different, he didn't get that in the mainstream of society.  So, he got in with a bunch of kooks and he looked pretty normal and as a matter of fact he could stand out and be a leader in that group of right wing conspiracy kooks.  He was relatively smart and he was also very guliible at the same time.  He was perfect lacky for the nut jobs that he associated with.\n\nHe was a model soldier in the U.S. Army because he was gun ho and followed orders, never questioned authority.  But when he was rejected by the Green Berets because he failed their grueling physical tests, he lost faith.  This rejection devasted him.  It created anger toward the American government and military.  He channeled his anger into right wing extremist hate groups.  The very reasons which made him a great soldier for the Army then made him a solider for right wing hate groups.
