Thou shalt not kill
Roman Catholic doctrine
This commandment demands respect for human life and is more accurately translated as "thou shalt not murder." Killing may, under limited circumstances, be justified within Catholicism. The basis of all Catholic teaching about the fifth commandment is the "sanctity of life", which is often contrasted with the "quality of life" to some extent. The Church is actively involved in the public debates over abortion, capital punishment and euthanasia, and encourages believers to support legislation and politicians it describes as pro-life.
