You are incorrect.
“Two teams of court-appointed psychiatrists examined Breivik prior to his trial; in the first report Breivik was diagnosed with paranoid schizophrenia, and a second evaluation was commissioned following widespread criticism of the first report. The second psychiatric evaluation was published one week before the trial, concluding that Breivik was not psychotic during the attacks nor during the evaluation; he was diagnosed with narcissistic personality disorder.”
Being familiar with mental health I can tell you there is absolutely no way to conclude if Breivik was experiencing a psychotic episode when he went on rampage or not. The criticisms of the first study were based more on public sentiment and judicial expediency.
