As the other fellow pointed out Rome and Britain furthered civilisation. Rome caused many tribal wars to stop because both tribes were Rome now - roads were built, trade flourished. Entire Europe used to have a law based on Roman Law. And it was just - nothing like what we have today.

British also projected a lot of good into the world. Common sense, logic, objectivity - these are very british things. Yes they're not angels but who is? If you focus merely on the negative, you will never see the positive.
