Religions provide different ways of dealing with moral dilemmas. For example, there is no absolute prohibition on killing in Hinduism, which recognizes that it "may be inevitable and indeed necessary" in certain circumstances. In monotheistic traditions, certain acts are viewed in more absolute terms, such as abortion or divorce. Religion is not always positively associated with morality. Philosopher David Hume stated that, "the greatest crimes have been found, in many instances, to be compatible with a superstitious piety and devotion; Hence it is justly regarded as unsafe to draw any inference in favor of a man's morals, from the fervor or strictness of his religious exercises, even though he himself believe them sincere."
