Lol yes... I've heard some alternative explanations of this. The Ten Commandments are not recognized outside of Christianity. They are just some important general sounding rules in a book that is full of rules for Jews, who get into battles with other people at times. Many of those rules in the same book have prescribed punishments of stoning to death, as well. So clearly, killing is at least allowed for purposes of punishment and warfare. Common sense also tells us that no religion can realistically prohibit self-defense.
