Now, I'm not a psychologist/psychiatrist, but isn't pedophilia a
sexual preference rather than a mental illness? Pedophiles
know that their actions are wrong and go to great lengths to cover their tracks, thus they are not insane when they rape/kill their victims. Couey, Westerfield and Carlie Brucia's killer, Joseph Smith are child molesters/child killers who knew their actions were wrong and went to great lengths to cover their tracks. They were not insane, just evil child preditors.
Andrea Yates is very mentally ill and there is no comparison of her case to the pedophiles on this thread. Big difference.
