Evaluating a number of controversial cases involving euthanasia, sadomasochism, date rape, battered wives, and "innocent" aggressors, Vera Bergelson builds a theoretical foundation for reform. Her approach to comparative criminal liability takes into account the actions of both the perpetrator and the victim and offers a unitary explanation for consent, self-defense, and provocation. This innovative book supplies a practical and coherent mechanism for evaluating the impact of a victim's conduct on a perpetrator's liability in a variety of circumstances, including those that are now artificially excluded from comparative analysis.
