This was far more than an undisciplined child grown up. I have seen this before. I would bet anything that “Junior’s father SA’ed him, and his mother knew but did nothing to protect him. Hence, the unbridled rage, and his mother’s unwillingness to press charges against him in the past.

Comment:  He declared himself an alcoholic to his mother but was likely using drugs too.  Cocaine brings out the worst in people.  Add testosterone to this and you have a volatile person.  Especially if the guy was previously sexually assaulted as a child.  He basically murdered his father; tried to murder his girlfriend but the hotel worker intervened to save her life.  Who knows how many he would have murdered unrestrained.  If you would like more information on how the CIA creates psychopaths look at:  16 year old MKULTRA used in Reagan Assassination
