  # Had to change this method name, it didn't read well in my test suite.
  # t.should be_thou_shalt_not_kill??? Give me a break.  Not idiomatic Ruby!
  # *I* would't be caught dead with those specs on. 
  # def thou_shalt_not_kill
  #   true
  # end

  # Much more idiomatic.  Now my specs read like butter too. 
  # t.should be_a_person_who_does_not_commit_murder.
  def a_person_who_does_not_commit_murder
    true
  end

end

def murderer? <= the question mark is idiomatic ruby
true
end

person.should_not be_murderer

Your "thou shalt not kill" method doesn't make sense; I can't think of an equivalent method I'd write an use that way. But it actually does kind of sound like a test:

thou.should_not kill(thee)

The issue here is that the idiomatic method makes it clear that this is a state check. This is distinct from a identity check, such as:
thou = ChildOfGod.new
thou.should be_a_child_of_god

With all that said, yes: Yahweh probably would not have used RSpec as his Ten Commandments design tool. Granted. :)
