In a new developer diary (after the break), Director Hideki "Viewtiful" Kamiya explains that Bayonetta and her fellow witches have suffered through torture themselves, and so she fights not only for survival, but for revenge. Her sadism is a direct result of her own experience previous to the game's events. Plus, as Kamiya says, "It is important players enjoy seeing enemies sadistically destroyed." Do try to enjoy the torture. Otherwise you'll be doing the cruelest attack of all: hurting Kamiya's feelings.
