According to Taraborrelli, the defining moment of Madonna's childhood was the tragic and untimely death of her beloved mother. Psychiatrist Keith Ablow suggests her mother's death would have had an immeasurable impact on the young Madonna at a time when her personality was still forming. According to Ablow, the younger a child is at the time of a serious loss, the more profound the influence and the longer lasting the impact. He concludes that "some people never reconcile themselves to such a loss at an early age, Madonna is not different than them." Conversely, author Lucy O'Brien feels the impact of the rape she suffered is, in fact, the motivating factor behind everything Madonna has done, more important even than the death of her mother: "It's not so much grief at her mother's death that drives her, as the sense of abandonment that left her unprotected. She encountered her own worst possible scenario, becoming a victim of male violence, and thereafter turned that full-tilt into her work, reversing the equation at every opportunity."
