In the course of the assessment (which takes the form of the cadet performing the role of a street judge with full powers), Kraken killed a group of Democracy terrorists who had taken hostages. Shortly afterwards Judge Morphy, Dredd's best friend and mentor (who had supervised Dredd on his own Final Assessment), was killed on a routine vehicle stop. Furious, Dredd almost murdered one of the perpetrators, pulling back at the last moment when Kraken urged him to control himself. Despite Kraken's impeccable performance, Dredd's unappealable decision was to fail him, believing that "a leopard can't change its spots. Not this one, anyway." At the moment of announcing his verdict, Dredd tendered his resignation and requested permission to take the Long Walk, leaving the city forever.
