To whom would Nichiren adjucate blame?

Nichiren states, "And that will in no way be her fault, but solely the result of his own reprehensible behavior." Most of the victims of the Soka Gakkai's only fault was seeking to sincerely practice the Lotus Sutra while having the misfortune to encounter the reprehensible behavior of leaders of a thought controlling personality cult. I know to whom Nichiren would adjudicate blame and it wouldn't be on the victims.
