While the indiscriminate taking of life is condemned by major religions and ethical systems worldwide, killing in some well defined situations is less clearly condemned. For example, most major religious traditions put killing in war in a separate category. Euthanasia, which the Netherlands legalized in 2000, is passionately debated. Probably today's most debated means of taking life is abortion. Although miscarriage is also known as spontaneous abortion, for the purposes of this discussion abortion means not the unintentional loss of a fetus but a purposeful termination of pregnancy.
